Quality Control

Our 7-Chloro-3,4-Dihydro-2H-Chromen-4-Amine is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via spectroscopic methods, to ensure it meets the high standards required for research and development applications. Certificates of Analysis (COA) with detailed batch-specific data are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed and consideration should be given to storage under an inert atmosphere for long-term preservation of quality.
