Quality Control

Our production of Butanoic Acid, (Chloromethyl)Dimethylsilyl Ester adheres to stringent quality management protocols. Each batch undergoes rigorous analytical testing, including chromatography (GC/HPLC) and spectroscopic methods (NMR, IR), to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing all relevant specifications are provided and can be tailored to meet specific customer or regulatory requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at room temperature (15-25°C). This compound is hygroscopic (moisture-sensitive); containers must be kept tightly sealed and under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent hydrolysis and degradation. Keep away from heat, sparks, open flames, and incompatible materials such as strong bases and oxidizing agents.
