Quality Control

Our Cyclohexanecarbonyl Chloride, 2-Methyl-5-(1-Methylethyl)-, [1R-(1Alpha,2Alpha,5Beta)]- (9Ci) is manufactured under strict quality management systems to ensure batch-to-batch consistency and high enantiomeric purity. Each lot undergoes comprehensive analytical testing, including chiral HPLC, NMR, and GC analysis, to confirm identity, purity, and the absence of critical impurities. A detailed Certificate of Analysis (COA) documenting all test results is provided with every shipment.

Storage

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