Quality Control

Our 7-Hydroxy-4-Methylcoumarin, Sodium Salt is manufactured under a strict quality management system. Each batch is tested to ensure it meets the 98% minimum purity specification and is free from critical impurities. Comprehensive testing includes identification, assay, and impurity profile analysis via HPLC and other validated methods. A Certificate of Analysis (COA) documenting all test results is provided with every shipment to ensure traceability and compliance for your regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture.
