Quality Control

Our Butanoic Acid, 2-Chloro-3-Oxo-, 1,1-Dimethylethyl Ester is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including chromatography (HPLC/GC) and spectroscopic methods (NMR, IR), to ensure identity, purity, and consistency. Certificates of Analysis (COA) with detailed batch-specific results are provided to guarantee it meets the high-purity standards required for research and synthesis applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area. Recommended storage temperature is between 2°C and 8°C (refrigerated) to maintain stability and extend shelf life. Keep away from heat, sparks, and open flame. Ensure the container is kept tightly sealed to prevent moisture absorption.
