Quality Control

Our 2-Amino-5-Nitrobenzenethiol is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation via FT-IR and NMR spectroscopy, to ensure it meets the high standards required for synthetic applications. A detailed Certificate of Analysis (COA) is provided with every shipment, guaranteeing traceability and consistent batch-to-batch quality.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at a controlled room temperature (15-25°C). Due to its sensitivity to oxidation, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation. Keep away from strong oxidizing agents.
