Quality Control

Our Palmitoleoyl Chloride is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including assay by titration and impurity profile analysis by GC/HPLC, to ensure it meets the high-purity standards required for sensitive synthetic applications. A Certificate of Analysis (COA) detailing purity, identity, and specific test results is provided with every shipment to guarantee traceability and consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at 2-8°C under an inert atmosphere (e.g., nitrogen or argon). Due to its hygroscopic and moisture-sensitive nature, containers must be kept sealed and handled under dry conditions to prevent hydrolysis. Keep away from strong bases, oxidizers, and sources of ignition.
