Sourcing 1-(2,3-Dichlorophenyl)Piperazine HCl: In-S
Technical Specifications and Purity Grades of 1-(2,3-Dichlorophenyl)piperazine HCl
When sourcing 1-(2,3-Dichlorophenyl)piperazine hydrochloride, also known as DCPP-Hydrochloride or Dichlorophenylpiperazine HCl, the first critical evaluation point is the purity profile. This phenylpiperazine derivative serves as a key organic synthesis intermediate in the production of various active pharmaceutical ingredients. Industrial buyers typically encounter two primary grades: technical grade (≥98%) and high-purity grade (≥99.5%). The difference lies not only in the main component assay but also in the control of specific related substances, such as positional isomers and des-chloro impurities, which can significantly impact downstream reaction yields. Our manufacturing process is optimized to consistently deliver material exceeding 99.5% purity by HPLC, with strict limits on individual unknown impurities (≤0.10%) and total impurities (≤0.5%). For applications requiring even tighter specifications, we offer custom purification runs to meet unique impurity thresholds. The table below provides a comparative overview of standard grades available in the market.
| Parameter | Technical Grade | High-Purity Grade | Custom Grade (Example) |
|---|---|---|---|
| Assay (HPLC, %) | ≥98.0 | ≥99.5 | ≥99.8 |
| Water Content (KF, %) | ≤1.0 | ≤0.5 | ≤0.2 |
| Related Substances | Reported | Controlled (RRT list) | Tailored to client specs |
| Residual Solvents | Meets USP <467> | Class 3 only | Class 3 only, low ppm |
| Appearance | Off-white powder | White to off-white powder | White crystalline powder |
It is essential to request a detailed COA that includes not just the assay but also the chromatographic purity profile. As a global manufacturer, we provide batch-specific COAs with every shipment, ensuring full traceability from raw material to final product. Our quality assurance system is built on ICH guidelines, and we offer comprehensive technical support to assist with method transfer and impurity identification.
Analytical Methods and COA Parameters for Quality Assurance
Robust analytical methods are the backbone of quality assurance for 1-(2,3-Dichlorophenyl)piperazine HCl. The industry-standard technique for assay and purity determination is reversed-phase HPLC with UV detection. A typical method employs an octadecylsilane (C18) bonded silica column (250 × 4.6 mm, 5 µm) with a mobile phase consisting of acetonitrile and phosphate buffer at a controlled pH. Gradient elution is often necessary to separate the main peak from structurally similar impurities, such as the 2,4-dichloro isomer or the mono-chloro analog. Our in-house validated method achieves baseline resolution between the target compound and all known related substances, with a limit of quantification (LOQ) below 0.05%. In addition to HPLC, we routinely perform Karl Fischer titration for water content, headspace GC for residual solvents, and residue on ignition for inorganic impurities. For clients requiring additional characterization, we can provide LC-MS, NMR, and XRD data. The COA we issue includes, at minimum: appearance (visual), identification (IR), assay (HPLC), water (KF), related substances (HPLC), residual solvents (GC), and heavy metals (ICP-MS). We understand that for many procurement managers, the COA is the primary document for incoming material acceptance. Therefore, we ensure that our COA format aligns with common pharmacopoeial standards, facilitating seamless integration into your quality system. When evaluating a new source, always request a pre-shipment sample and compare the COA against your internal specifications. This practice mitigates the risk of batch-to-batch variability and ensures consistent performance in your synthesis route.
Industrial Handling and Bulk Packaging Solutions
Proper handling and packaging are critical to maintaining the integrity of 1-(2,3-Dichlorophenyl)piperazine HCl during storage and transport. This material is hygroscopic and should be stored in a cool, dry environment (recommended 2–8°C) under inert gas. For bulk price inquiries, we offer a range of packaging options tailored to industrial needs: 25 kg fiber drums with double LDPE liners, 50 kg HDPE drums, and 500 kg or 1000 kg IBC totes. All packaging is UN-approved and suitable for international shipping. We have extensive experience in logistics to major pharmaceutical hubs, and we can arrange door-to-door delivery under controlled conditions. While we do not claim specific environmental certifications, our packaging is designed to minimize physical damage and moisture ingress. For large-volume contracts, we can implement dedicated packaging lines to reduce cross-contamination risks. Our logistics team works closely with clients to optimize shipping schedules and consolidate orders, reducing overall landed costs. When discussing industrial purity and handling, it is important to note that the material may develop a slight electrostatic charge during transfer, which can lead to clumping or adherence to equipment surfaces. This is a known behavior for fine organic powders and can be mitigated by using grounded equipment and controlling humidity. For more detailed guidance, refer to our article on excipient compatibility and static charge control.
Supply Chain Reliability and Drop-in Replacement Strategy
In today's volatile market, supply chain reliability is paramount. As a dedicated manufacturer of 1-(2,3-Dichlorophenyl)piperazine HCl, we position our product as a seamless drop-in replacement for existing qualified sources. This means that our material is manufactured to match the critical quality attributes of the incumbent supplier, including particle size distribution, polymorphic form, and impurity profile. We achieve this through rigorous process control and a deep understanding of the manufacturing process. Our production facility operates under strict quality management systems, and we maintain significant safety stock of key intermediates to buffer against raw material shortages. For buyers, switching to a new supplier often involves costly requalification. We minimize this burden by providing comprehensive technical data packages, including method equivalency studies and comparative impurity profiling. Our technical team is available to support your analytical method transfer and can provide reference standards for impurity identification. By choosing our product, you gain a cost-efficient alternative without compromising on quality or regulatory compliance. We understand that the term "RARECHEM AH CK 0082" is sometimes used in catalog sourcing; our material is fully equivalent to this reference and can be used interchangeably in established synthetic procedures. For insights into managing specific process challenges, such as salt precipitation during DMF coupling, see our article on managing salt precipitation in DMF coupling. Our commitment to supply chain transparency means you will always know the status of your order, from production to delivery.
Non-Standard Parameters and Field Experience Insights
Beyond the standard specifications, field experience reveals several non-standard parameters that can impact the performance of 1-(2,3-Dichlorophenyl)piperazine HCl in sensitive applications. One such parameter is the material's behavior at sub-zero temperatures. While the bulk powder is stable, we have observed that residual solvent levels, even within ICH limits, can influence the glass transition temperature of the amorphous phase, potentially leading to caking if the product is stored in unheated warehouses during winter. To mitigate this, we recommend specifying a maximum residual solvent content of 0.3% for long-term storage in cold climates. Another edge-case behavior relates to trace metal impurities, particularly iron and copper, which can catalyze unwanted side reactions in certain coupling steps. Although our standard product meets the USP <231> limit, we can provide material with ultra-low metal content (<10 ppm) upon request. Additionally, the color of the final product can vary from white to a pale beige depending on the drying conditions and trace oxidation. While this does not affect chemical purity, some automated visual inspection systems in downstream formulation may flag off-white batches. We can control the color to a consistent white by optimizing the drying parameters and using inert atmosphere packaging. These insights come from years of collaboration with process chemists and highlight the importance of open communication between supplier and user. When sourcing, do not hesitate to discuss these non-standard requirements; a knowledgeable manufacturer will be able to accommodate them.
