Description

2-Chloro-1,3-Butadiene is a highly reactive chlorinated diene monomer, a key building block in specialty polymer synthesis. Its unique structure, combining a conjugated diene system with a reactive chlorine atom, makes it an essential intermediate for creating polymers with specific chemical resistance and elastomeric properties. This compound is primarily utilized by manufacturers in the synthetic rubber, specialty adhesives, and polymer modification industries seeking to enhance material performance.

Application

• Primary monomer for the production of polychloroprene (Neoprene) synthetic rubber.
• Intermediate in the synthesis of specialty adhesives and sealants requiring oil and weather resistance.
• Chemical intermediate for manufacturing modified polymers and resins.
• Component in the production of specialty elastomers for automotive and industrial hoses, belts, and gaskets.
• Used in research and development for novel copolymer systems.
• Starting material for certain agrochemical and pharmaceutical intermediates.

Quality Control

Our 2-Chloro-1,3-Butadiene is produced and handled under stringent quality management systems to ensure batch-to-batch consistency and reliability for industrial polymerization processes. Quality is verified through comprehensive analytical testing including gas chromatography (GC) for purity and assay, and tests for stabilizer content and moisture. Certificates of Analysis (COA) detailing all relevant specifications are provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources, sparks, and open flame. Due to its highly volatile and light-sensitive nature, containers should be kept tightly sealed under an inert atmosphere (e.g., nitrogen) and at recommended temperatures to prevent polymerization and maintain stability. Keep separated from strong oxidizing agents.
