Quality Control

Our Butyric Acid 2-Chloro-1-(Chlorodifluoromethyl)-2,2-Difluoroethyl Ester is produced and handled under strict quality management protocols. Each batch undergoes rigorous analytical testing to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing specifications such as assay (by GC or HPLC), identity (IR, NMR), and impurity profiles are available upon request. We are committed to meeting the exacting standards required for research and scale-up applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and incompatible materials. Due to its properties as a strong acid/organic solvent and high volatility, ensure containers are sealed and stored upright. Recommended storage temperature is 2-8°C for long-term stability, although short-term storage at controlled room temperature (15-25°C) is acceptable. Keep away from strong bases, oxidizing agents, and moisture.
