Quality Control

Every batch of Cholesteryl Parinarate is produced and analyzed under stringent quality protocols to ensure the high purity and consistency required for sensitive research applications. Our products undergo rigorous quality testing, including chromatographic purity analysis and spectroscopic identification, to ensure compliance with exacting research standards. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and specific tests is provided with each shipment and is available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below under an inert atmosphere (e.g., argon or nitrogen) in a dry, moisture-free environment to prevent oxidation and hydrolysis. For long-term stability, it is recommended to store desiccated. Allow the sealed container to reach room temperature before opening to minimize condensation and moisture ingress.
