Quality Control

Our 7-Amino-2-(4-(Dimethylamino)Phenyl)-8-Nitro-4H-Chromen-4-One is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via spectroscopic methods (NMR, IR, MS), to ensure it meets the high standards required for research and development applications. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment.

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 light-sensitive nature and propensity to be easily oxidized, it is recommended to store the material under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation. Keep away from heat and incompatible materials.
