Technical Specifications and Bulk Procurement of 2-Chloro-5-fluoro-4-iodopyridine
- Verified Purity: Guaranteed >98% assay via HPLC and NMR analysis.
- Regulatory Compliance: Full documentation package including COA and MSDS.
- Scalable Supply: Industrial manufacturing capacity for global pharmaceutical partners.
In the landscape of modern medicinal chemistry, the demand for highly specialized heterocyclic compounds continues to rise. Among these, the Halogenated pyridine class represents a critical segment due to its versatility in cross-coupling reactions and scaffold diversification. Specifically, 2-Chloro-5-fluoro-4-iodopyridine (CAS: 884494-49-9) serves as a vital pharmaceutical intermediate for the development of kinase inhibitors and agrochemical agents. Procurement teams prioritizing reaction yields and process safety require a partner capable of delivering consistent industrial purity alongside robust regulatory support.
At NINGBO INNO PHARMCHEM CO.,LTD., we understand that the quality of the starting material directly influences the success of the final Active Pharmaceutical Ingredient (API). This technical overview details the verification standards, documentation protocols, and quality benchmarks associated with sourcing this high-value organic building block.
HPLC and NMR Verification Standards
Ensuring the structural integrity and purity of multi-halogenated heterocycles requires rigorous analytical validation. Standard quality control protocols for this Pyridine derivative involve high-performance liquid chromatography (HPLC) and nuclear magnetic resonance (NMR) spectroscopy. These methods confirm not only the assay percentage but also the absence of regioisomers and residual solvents that could interfere with downstream synthesis.
Our manufacturing process utilizes optimized chromatographic conditions to separate the target compound from potential byproducts such as di-iodinated species or dehalogenated impurities. The typical acceptance criteria for bulk orders include:
- HPLC Purity: Minimum 98.0% area normalization.
- Water Content: Karl Fischer titration showing <0.5%.
- Residual Solvents: Compliant with ICH Q3C guidelines.
- Heavy Metals: <10 ppm total impurities.
For research teams requiring validated specifications for 2-Chloro-5-fluoro-4-iodopyridine, our facility ensures that every batch undergoes double-blind verification before release. This level of scrutiny minimizes the risk of reaction failure during critical scale-up phases, particularly when employing palladium-catalyzed coupling reactions where iodine selectivity is paramount.

| Package | 25kg / 50kg Drum | Visual / Weight |
Regulatory Documentation and COA Details
In the global supply chain, technical excellence must be matched by comprehensive documentation. A Certificate of Analysis (COA) is not merely a formality; it is a legal and technical guarantee of product quality. For a complex organic building block like this, the COA must detail the specific batch number, manufacturing date, and exact results for all critical quality attributes.
Buyers often encounter variability in the depth of documentation provided by different suppliers. Some may offer generic templates, whereas a dedicated global manufacturer provides batch-specific data linked to retained samples. This traceability is essential for regulatory filings, such as Drug Master Files (DMF) or Investigational New Drug (IND) applications. Our documentation package typically includes:
- Certificate of Analysis: Full quantitative results for the specific batch.
- Material Safety Data Sheet (MSDS): Handling, storage, and emergency measures.
- Statement of Origin: Confirmation of synthetic route and raw material sourcing.
- Stability Data: Recommended re-test periods under defined storage conditions.
Proper storage is critical for maintaining the stability of halogenated pyridines. These compounds should be kept in tightly sealed containers, protected from light and moisture, at temperatures below 25°C. Deviation from these conditions can lead to hydrolysis or oxidation, compromising the industrial purity required for sensitive catalytic cycles.
Purity Comparison Against Market Competitors
When evaluating suppliers, procurement managers must look beyond the stated purity percentage. Market analysis indicates significant variance in the actual performance of materials labeled as 98% pure. Lower-grade materials often contain hidden impurities, such as isomeric contaminants or residual catalysts, which are not always disclosed on standard certificates.
These impurities can poison catalysts in Suzuki or Buchwald-Hartwig couplings, leading to reduced yields and increased purification costs downstream. Our synthesis route is designed to minimize these specific byproducts through precise halogenation control and recrystallization processes. The table below illustrates the typical quality differentiators found in the market:
| Quality Parameter | Standard Market Grade | NINGBO INNO Premium Grade |
|---|---|---|
| HPLC Purity | 95% - 97% | ≥ 98.5% |
| Isomeric Impurities | Up to 3% | < 0.5% |
| Catalyst Residues | Not Specified | Tested < 5 ppm |
| Documentation | Generic COA | Batch-Specific Full Data |
| Lead Time | Variable (4-8 Weeks) | Stocked / 2-4 Weeks |
