Quality Control

Our 3-Amino-4,7-Dihydroxycoumarin Hydrochloride is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high purity. We employ advanced analytical techniques, including HPLC and NMR, to verify identity and potency. Certificates of Analysis (COA) detailing purity, impurities, and other critical parameters are provided with every shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This compound is hygroscopic (moisture-sensitive); therefore, the container must be kept tightly sealed to prevent degradation from atmospheric moisture.
