Quality Control

Our Methyl 4-{[(3-Allyl-5,6-Dimethyl-4-Oxo-3,4-Dihydrothieno[2,3-D]Pyrimidin-2-Yl)Sulfanyl]Methyl}Benzoate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and MS, to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing all specifications are provided and can be tailored to meet specific client requirements or internal standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its light-sensitive and easily oxidized nature, it is recommended to store the material under an inert atmosphere (e.g., nitrogen or argon) for long-term stability. Keep away from heat, sparks, and open flame.
