Quality Control

Our 3,4-Dihydro-2-(4-Hydroxyphenyl)-2H-1-Benzopyran-4-Ol is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure identity, purity, and consistency. A comprehensive Certificate of Analysis (COA) detailing purity (typically >97% by HPLC), physical characteristics, and impurity profiles is provided with every shipment to guarantee it meets your specific R&D or production requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Due to its light-sensitive and easily oxidized nature, it is recommended to store the material under an inert atmosphere (e.g., nitrogen or argon) for long-term stability. Keep away from strong oxidizing agents.
