Quality Control

Our Benzo[B]Thiophene-2,3-Diamine, 4,5,6,7-Tetrahydro- (9Ci) is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, GC, and NMR, to ensure high purity and batch-to-batch consistency essential for research and scale-up. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are 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 hygroscopic nature, the container must be kept tightly sealed after each use to prevent moisture absorption, which can affect stability and purity. Keep away from strong oxidizing agents.
