Quality Control

Our 7-Mercapto-2-Phenyl-5H-Pyrazolo[1,5-D][1,2,4]Triazin-4-One is manufactured under strict quality management systems. Every batch undergoes comprehensive analytical testing, including HPLC for purity, NMR and IR for structural confirmation, and residual solvent analysis, to ensure it meets the high standards required for research and synthesis. Certificates of Analysis (COA) with detailed specifications are provided for full traceability and quality assurance.

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