Quality Control

Our 2-Mercapto-4,6-dimethoxypyrimidine is manufactured under strict quality management systems. Every batch undergoes comprehensive analytical testing, including HPLC, NMR, and IR spectroscopy, to ensure high purity and consistent performance. Certificates of Analysis (COA) detailing all specifications are provided with each 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 place at room temperature (15-25°C). Due to its light-sensitive nature and propensity to be easily oxidized (store under inert atmosphere), it is recommended to handle under an inert atmosphere such as nitrogen for long-term storage or after opening.
