Quality Control

Our 4H-1-Benzopyran-4-One, 7-(Bromomethyl)- is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity, NMR and IR for structural confirmation, and residual solvent analysis. We provide a detailed Certificate of Analysis (COA) with every shipment to ensure traceability and compliance with your research or production specifications.

Storage

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