Quality Control

Our 9-cis-Retinyl Palmitate is manufactured under strict quality systems to ensure high purity and isomer specificity. Each batch is supported by a comprehensive Certificate of Analysis (COA) detailing identity, purity by HPLC, and isomer content. We adhere to cGMP principles for pharmaceutical-grade materials, ensuring traceability and consistency for research and development applications.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at 2-8°C (refrigerated) or as specified on the certificate. This product is light-sensitive (store away from light) and easily oxidized (store under inert atmosphere). Keep the container tightly sealed in a dry, cool, and well-ventilated place.
