Quality Control

Our 5-Chloro-8-Hydroxy-6-Methoxy-3-Methyl-1H-2-Benzopyran-1-One is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and mass spectrometry, to ensure identity, purity, and consistency. Certificates of Analysis (COA) documenting all critical parameters are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (typically 15-25°C). Keep away from incompatible materials. Due to its light-sensitive nature, containers should be amber-colored or stored in light-resistant secondary packaging.
