For procurement managers and R&D scientists in the chemical and pharmaceutical industries, sourcing high-quality raw materials is paramount. 1,3-Dichloropropane (CAS 142-28-9) stands out as a critical organic synthesis intermediate and solvent. Understanding how to effectively source this compound can significantly impact project success and cost-efficiency. This guide focuses on what buyers should look for when seeking a reliable manufacturer and supplier.

Understanding the Needs: Purity and Specifications

When looking to buy 1,3-Dichloropropane, the first consideration is purity. While various grades exist, for demanding applications such as pharmaceutical synthesis or advanced material research, a high assay of ≥99.5% is often required. This level of purity ensures minimal side reactions and predictable outcomes in your chemical processes. Always request a Certificate of Analysis (CoA) from your supplier to verify these specifications. Key properties to confirm include its appearance (typically a clear, colorless liquid), water content, and absence of critical impurities.

The Role of 1,3-Dichloropropane in Organic Synthesis

As a bifunctional haloalkane, 1,3-Dichloropropane is invaluable for a range of organic transformations. It acts as a crucial building block for introducing specific carbon chains and facilitating cyclization reactions. For instance, it is instrumental in synthesizing complex molecules, including certain agrochemical and pharmaceutical intermediates. Its utility as a solvent in various reactions and its application in detergents and chromatographic analysis further underscore its importance. When researching 1,3-Dichloropropane uses, consider its reactivity and compatibility with other reagents in your specific synthesis.

Navigating the Supplier Landscape in China

China has emerged as a global hub for chemical manufacturing. When searching for a 1,3-Dichloropropane supplier in China, look for established companies with a proven track record in producing fine chemicals and intermediates. Key indicators of reliability include ISO certifications, strong quality control systems, and transparent communication. A reputable manufacturer will not only offer competitive 1,3-Dichloropropane price points but also provide robust technical support and efficient logistics. Engaging with suppliers that offer samples for testing is also a wise strategy to ensure the material meets your exact requirements.

Key Considerations for Procurement

Beyond purity and supplier reputation, consider packaging and storage. 1,3-Dichloropropane is typically supplied in drums (e.g., 220KG/drum). Proper storage, as advised by the manufacturer, involves keeping the container sealed in a cool, dry, and well-ventilated warehouse, away from oxidizing agents. For large-scale procurement, understanding the supplier's lead times and shipping capabilities is crucial for maintaining production continuity. By focusing on these aspects, procurement managers can secure a consistent and high-quality supply of 1,3-Dichloropropane, empowering their research and manufacturing operations.
