Quality Control

Our 1H-Indole-4,6-Diamine is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. We provide comprehensive analytical data, including HPLC purity, identity confirmation (IR, NMR), and residual solvent analysis. A Certificate of Analysis (COA) is supplied with each batch, detailing all test results against our stringent internal specifications.

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 opening to minimize exposure to atmospheric moisture. Keep away from incompatible materials such as strong oxidizing agents.
