Quality Control

Our 6-Amino-4-Chloro-3-Hydroxy (1H)Indazole is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC, NMR, and mass spectrometry, to ensure identity, purity, and consistency. We provide Certificates of Analysis (COA) with detailed specifications for trace impurities, residual solvents, and heavy metals, supporting its use in regulated research and development.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to prevent moisture absorption, which may affect stability and handling properties.
