Quality Control

Our 3-Amino-7-Chloro-5-Nitro-1H-Indazole is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity, NMR and IR for structural confirmation, and residual solvent analysis. We provide a detailed Certificate of Analysis (COA) with every shipment, ensuring traceability and compliance with your research and development 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 prevent moisture absorption, which may affect stability and performance.
