Quality Control

Our 2-Butanone, 4-(Acetyloxy)-1-Chloro- is produced and handled under strict quality management protocols. Each batch undergoes rigorous analytical testing to ensure identity, purity, and consistency. We provide comprehensive Certificates of Analysis (COA) with key parameters including assay (by HPLC or GC), impurity profile, and physical characterization. Our quality commitment supports applications requiring high-purity intermediates for research and regulated synthesis.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials such as strong acids, bases, and oxidizing agents. Recommended storage temperature is between 2°C and 8°C for extended stability, although short-term storage at controlled room temperature (15-25°C) may be acceptable. Keep container tightly sealed when not in use to prevent moisture absorption and volatilization.
