Quality Control

Our 4-Amino-6-Hydroxy-2-Mercapto-5-Nitrosopyrimidine is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and elemental analysis, to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing all specifications are provided with every shipment to support your quality assurance and regulatory compliance needs.

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 sensitivity to oxidation, prolonged storage under an inert atmosphere (e.g., nitrogen or argon) is recommended for optimal long-term stability. Keep away from incompatible materials.
