High Purity Industrial 3-Chloropropyne with Competitive Ex-Factory Cost

3 - Chloropropyne is a highly reactive halogenated alkyne and a key pharmaceutical intermediate. It contains an acetylene bond and a chlorine substituent within its molecule, exhibiting excellent reactivity in nucleophilic substitution and cycloaddition reactions, and is widely used in the synthesis of various heterocyclic drug molecules. In the pharmaceutical sector, it is primarily used to construct target drug skeletons containing acetylene groups, nitrogen-containing heterocycles, and furan rings. It is employed in the production of intermediates for antifungal drugs, anti-inflammatory drugs, and central nervous system modulators. Functional side chains can be introduced through dehalogenation and coupling reactions to enhance the biological affinity of drug molecules. In the fine chemicals sector, it serves as a specialty organic synthesis building block for the preparation of liquid crystal monomers and photolithography-related electronic chemicals. Thanks to its unsaturated alkyne structure, it is well-suited for polymerization and modification reactions. It can also function as a raw material for the synthesis of agricultural heterocyclic fungicides and is used in the preparation of small-molecule antimicrobial active intermediates. This raw material requires mild reaction conditions, allows for easy separation of byproducts, and enables controlled purity of the final product. It is suitable for continuous chemical production lines, poses no risk of heavy metal impurity residue, and meets pharmaceutical-grade quality control standards. As a key raw material for niche, high-value-added custom synthesis, it enjoys stable demand from overseas fine chemical and API contract manufacturing facilities.

The product strictly complies with the GB/T 2961-2014 national standard, accompanied by a complete set of MSDS, commodity inspection reports, and hazardous packaging certificates, and meets EU REACH import and export requirements. Standard packaging includes 200 kg galvanized closed-top steel drums and 1,000 L IBC containers. For large volumes, bulk transport via tank containers is available. Storing and transporting the product in a sealed, light-protected environment effectively delays oxidation and discoloration. Supply is stable and ample, supporting full-container and consolidated shipments for international trade, and meeting global chemical procurement and custom fine chemical production needs.
