Quality Control

Our 6-Mercapto-1-Phenyl-1,5-Dihydro-4H-Pyrazolo[3,4-D]Pyrimidin-4-One is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including HPLC, NMR, and MS, to ensure identity, purity, and consistency. Certificates of Analysis (COA) with full traceability are provided to support your research and regulatory requirements.

Storage

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