Quality Control

Our 8,8'-Diapo-ψ,ψ-Carotene-8,8'-Dioic Acid 8-Methyl Ester is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via spectroscopic methods, to ensure it meets exacting standards for research and synthesis. Certificates of Analysis (COA) detailing purity, impurities, and full analytical data are provided with every shipment.

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) to minimize oxidation. The container should be kept in a cool, dry, and well-ventilated area, away from heat sources and incompatible materials.
