Quality Control

Our 2-Butanone, 3-Chloro-4,4-Diethoxy- is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including chromatography (HPLC/GC) and spectroscopic methods (NMR, IR), to ensure identity, purity, and consistency. We provide comprehensive Certificates of Analysis (COA) with every shipment, detailing all specified parameters. Our quality system is designed to meet the stringent requirements of cGMP for pharmaceutical intermediates and ISO standards for industrial applications.

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 oxidizing agents, strong bases, and strong acids. Recommended storage temperature is between 2°C and 8°C for extended stability, although short-term storage at controlled room temperature (15-25°C) is acceptable. The container should be kept tightly sealed to prevent moisture absorption and volatilization.
