Quality Control

Our 5-Amino-6-Hydroxy-4-Oxo-4H-1-Benzopyran-2-Carboxylic Acid Ethyl Ester is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing purity (typically >95% by HPLC), residual solvents, and other critical parameters are available upon request, supporting 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 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.
