Quality Control

Our Cholesteryl Benzoate is produced under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including HPLC for assay and purity determination, to meet the stringent requirements of research and industrial applications. A Certificate of Analysis (COA) detailing specific test results is provided with every shipment to guarantee compliance with your specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). This material is light-sensitive and easily oxidized; for long-term storage, it is recommended to keep the container under an inert atmosphere such as nitrogen or argon to maintain stability and prevent degradation.
