Quality Control

Our 1-(4-Chloro-Phenyl)-1H-Tetrazole-5-Thiol is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via FT-IR and NMR spectroscopy, to ensure it meets the high standards required for research and industrial synthesis. Certificates of Analysis (COA) detailing batch-specific results are provided with every shipment to guarantee traceability and consistency.

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 light-sensitive nature and propensity for oxidation, it is recommended to store the material under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation. Keep away from strong oxidizing agents.
