Quality Control

Our (+)-Mod-Diop is produced under strict quality management protocols to ensure batch-to-batch consistency and high enantiomeric purity. Each lot undergoes comprehensive analytical testing, including chiral HPLC and NMR, to verify identity and purity. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry place at room temperature (15-25°C). Due to its sensitivity to oxidation, the container should be purged with inert gas after each opening to maintain product integrity.
