Quality Control

Our 3-Allyl-2-Mercaptothieno[3,2-D]Pyrimidin-4(3H)-One is produced under a strict quality management system. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and MS, to ensure high purity and structural identity. Certificates of Analysis (COA) detailing all specifications are provided with every shipment to guarantee traceability and batch-to-batch consistency for your critical R&D and scale-up processes.

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 sensitivity to oxidation, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation. Keep away from heat and incompatible materials.
