Quality Control

Every batch of 3-Cycloheptene-1-Carbonyl Chloride, 3,6,6-Trimethyl-7-Oxo-, (S)- (9Ci) is manufactured and analyzed under strict quality management systems. We provide comprehensive Certificates of Analysis (COA) that detail purity, enantiomeric excess, and impurity profiles, ensuring the material meets the stringent requirements for advanced synthetic applications. Our quality protocols are designed to support cGMP and ISO standards for traceability and consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 2°C and 8°C (refrigerated) to maintain stability and minimize degradation. Due to its hygroscopic and highly volatile nature, the container must be kept sealed under an inert atmosphere (e.g., nitrogen or argon) when not in use. Keep away from strong acids, bases, and oxidizing agents.
