Quality Control

Our 2,3-Dimethyl-1,3-Butadiene is produced and handled under stringent quality management protocols to ensure batch-to-batch consistency and reliability for your critical processes. Each lot is analyzed to confirm identity, purity, and the absence of critical impurities like peroxides. A comprehensive Certificate of Analysis (COA) detailing specific test results is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat, sparks, and open flame. Due to its highly volatile and potentially polymerizable nature, it is recommended to store under an inert atmosphere (e.g., nitrogen) at temperatures preferably between 2°C and 8°C to maximize shelf-life and inhibit premature polymerization. Keep away from oxidizing agents and strong acids.
