Quality Control

Our 5-Mercapto-4-Methyl-4H-1,2,4-Triazol-3-Ol 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, to ensure it meets the high standards required for research and industrial synthesis. Certificates of Analysis (COA) with detailed batch-specific results are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its property of being easily oxidized, long-term storage under an inert atmosphere (e.g., nitrogen or argon) is recommended for optimal stability. Keep away from strong oxidizing agents.
