Quality Control

Every batch of 2-Amino-7-Bromo-5-Oxo-5H-(1)Benzopyrano is manufactured under a strict quality management system. Our products undergo rigorous quality testing, including HPLC, NMR, and mass spectrometry, to ensure high purity and batch-to-batch consistency that meets the stringent requirements of research and industrial applications. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with each shipment and is available upon request.

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). This product is hygroscopic (moisture-sensitive) and light-sensitive; therefore, containers must be kept tightly sealed after opening to minimize exposure to atmospheric moisture and light to maintain product integrity.
