Quality Control

Our 3-Chloro-2-Butanone is manufactured under stringent quality control protocols to ensure batch-to-batch consistency and high purity. We adhere to cGMP principles where applicable, and our quality management system is designed to meet the rigorous demands of industrial and research applications. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment to guarantee supply reliability and technical compliance.

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 properties as a strong acid/organic solvent and high volatility, it should be kept separate from incompatible materials such as strong bases and oxidizing agents. Recommended storage temperature is 2-8°C for extended stability.
