In the landscape of fine chemical manufacturing, securing a reliable supply of critical intermediates is paramount for maintaining production continuity and research accuracy. 1,3-Dichloropropane (CAS: 142-28-9), also known technically as Trimethylene dichloride, serves as a vital bifunctional alkylating agent in the synthesis of pharmaceuticals, agrochemicals, and specialty polymers. For procurement managers and process chemists, the distinction between commercial grade and high-purity industrial specifications can determine the success of a synthesis campaign. At NINGBO INNO PHARMCHEM CO.,LTD., we prioritize batch-to-batch consistency and transparent quality assurance to support large-scale organic transformations.
Technical Specifications and Impurity Profiles
For R&D teams scaling up reactions, the impurity profile of the raw material is as critical as the primary assay. Lower quality variants often contain residual acids, moisture, or isomeric byproducts that can catalyze unwanted side reactions or reduce overall yields. Our manufacturing process utilizes advanced distillation columns to isolate Propane 1,3-dichloro with exceptional clarity. We strictly monitor water content, as even trace moisture can interfere with moisture-sensitive organometallic steps often employed when using this chemical raw material.
When sourcing high-purity 1,3-Dichloropropane, buyers should prioritize suppliers who provide gas chromatography (GC) data alongside standard titration results. This dual-verification method ensures that the industrial purity claims are backed by empirical data regarding specific congeners. Our facility employs rigorous in-process controls to minimize the presence of 1,2-isomers or chlorinated oligomers, ensuring the material acts as a predictable organic intermediate.
Quality Parameters and Testing Protocols
To facilitate quick verification by quality control departments, we adhere to a standardized specification sheet. The following table outlines the typical technical parameters for our industrial grade output. These metrics are designed to meet the demands of both laboratory-scale research and full-scale production runs.
| Parameter | Specification | Test Method |
|---|---|---|
| Appearance | Clear, Colorless Liquid | Visual Inspection |
| Purity (GC Area %) | ≥ 99.5% | Gas Chromatography |
| Water Content | ≤ 0.05% | Karl Fischer Titration |
| Density (20°C) | 1.19 - 1.20 g/cm³ | ASTM D4052 |
| Refractive Index (20°C) | 1.440 - 1.445 | ASTM D1218 |
| Acidity (as HCl) | ≤ 0.005% | Titration |
Supply Chain Stability and Bulk Procurement
For procurement officers, supply chain resilience is a key metric. Market fluctuations can impact bulk price stability, but partnering with a dedicated global manufacturer mitigates these risks. We maintain substantial inventory levels of 1,3-Dichlor-propan to ensure immediate availability for urgent orders. Our logistics network supports various packaging configurations, typically supplying in 250kg drums or ISO tanks for larger volumes, ensuring safe transport compliant with international hazardous material regulations.
Transparency in the manufacturing process allows our clients to forecast their raw material needs accurately. We provide lead time guarantees and real-time shipment tracking. By eliminating intermediaries, we offer competitive pricing structures that reflect true factory-direct value without compromising on the quality assurance protocols that safeguard your production line.
Documentation and Regulatory Compliance
Executive decision-makers require assurance that all chemical inputs meet regulatory standards such as REACH and TSCA. Every shipment from NINGBO INNO PHARMCHEM CO.,LTD. is accompanied by a batch-specific Certificate of Analysis (COA), Safety Data Sheet (SDS), and Certificate of Origin (COO). This documentation is critical for customs clearance and internal audit compliance. Our quality assurance team verifies every batch against strict internal standards before release, ensuring that the COA reflects the actual contents of the delivered goods.
Proper storage is essential to maintain product integrity upon receipt. Similar to other chlorinated solvents, this material should be kept in a cool, dry, and well-ventilated warehouse, away from oxidizing agents and direct sunlight. Containers must remain sealed when not in use to prevent moisture absorption and volatilization.
Commitment to Technical Excellence
Whether you are developing a new synthesis route for a complex pharmaceutical ingredient or requiring a reliable solvent for industrial cleaning applications, the quality of your starting materials defines your output. We invite qualified buyers to request samples for validation testing.
