Quality Control

Our 2-Mercapto-3-(2-Methoxyethyl)-6,7-Dihydrothieno[3,2-D]Pyrimidin-4(3H)-One is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via spectroscopic methods (NMR, IR, MS), to ensure it meets the high standards required for pharmaceutical research. Certificates of Analysis (COA) with detailed batch-specific results are provided and can be tailored to meet client-specific requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at 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 incompatible materials.
