Quality Control

Our 2-Mercapto-3-(2-Methoxyphenyl)-3,5,6,7-tetrahydro-4H-cyclopenta[4,5]thieno[2,3-d]pyrimidin-4-one is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and mass spectrometry, to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing all specifications are provided with every shipment. We support compliance with research and development standards, and custom purity grades are available upon request.

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 the container tightly sealed in a dry environment to minimize exposure to moisture.
