Quality Control

Every batch of our (1S)-Camphanoyl Chloride is produced and tested under strict quality management systems. We provide comprehensive analytical data to ensure identity, purity, and enantiomeric excess meet the exacting standards required for advanced synthetic applications. Certificates of Analysis (COA) with detailed chromatographic and spectroscopic data (HPLC, GC, NMR) are available for each lot upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at temperatures between 2°C and 8°C (refrigerated). Due to its hygroscopic and moisture-sensitive nature, containers must be kept sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent hydrolysis. Keep away from heat, sparks, open flames, and strong bases.
