Quality Control

Our Thieno[3,2-D]Pyrimidine-7-Methanamine is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing, including HPLC, NMR, and MS, to ensure identity, purity, and consistency. We provide a detailed Certificate of Analysis (COA) with each shipment, documenting all critical quality attributes. Our production can adhere to cGMP standards for advanced pharmaceutical applications upon request.

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 hygroscopic nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent moisture absorption and degradation.
