Quality Control

Our cholesterol is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation via IR spectroscopy, to ensure it meets stringent specifications for research and industrial use. Certificates of Analysis (COA) are provided with every shipment, detailing all test results. We can supply material compliant with various pharmacopeial standards (e.g., USP, EP) upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This product is easily oxidized (store under inert atmosphere) and is light-sensitive. For long-term storage, consider storage under an inert gas such as nitrogen or argon to maintain optimal purity.
