Quality Control

Our Cyclohexanecarboxylic Acid, 2-(Chlorocarbonyl)-, Methyl Ester, (1S-Cis)- (9Ci) is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including chiral purity analysis by HPLC, to ensure high chemical and stereochemical purity suitable for sensitive synthetic applications. Certificates of Analysis (COA) with detailed chromatographic data are provided to guarantee traceability and batch-to-batch consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place. Due to its hygroscopic nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen) after opening to prevent moisture absorption and decomposition. Recommended long-term storage temperature is 2-8°C.
