Quality Control

Every batch of 4H-1-Benzopyran-4-One,5-Amino-2-(4-Aminophenyl)-(9Ci) is manufactured under a strict quality management system. We provide comprehensive analytical data to ensure the product meets the high standards required for research and commercial synthesis. Our products undergo rigorous quality testing to ensure compliance with industry standards. Certificates of Analysis (COA) are available upon request, detailing purity, identity, and impurity profiles as confirmed by HPLC, NMR, and MS.

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 after each use to prevent degradation from atmospheric moisture. Keep away from incompatible materials.
