Quality Control

Our 3-Hydroxycoumarin is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency. We provide a detailed Certificate of Analysis (COA) with every shipment, which includes results from HPLC, NMR, and other relevant tests to verify compliance with customer specifications and industry standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Due to its light-sensitive nature and propensity for oxidation, prolonged exposure to light and air should be minimized. For long-term storage, consider an inert atmosphere.
