Quality Control

Our Bisnorcholenaldehyde is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including identity confirmation by FT-IR and NMR, purity assessment by HPLC, and control of specific impurities. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to ensure traceability and compliance with your specifications.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at controlled room temperature (15-25°C) in a cool, dry, and well-ventilated place. This material is light-sensitive and easily oxidized; prolonged exposure to air or light should be avoided to maintain product integrity.
