Quality Control

Our Acetamide, 2-[(1,4-Dihydro-5,6-Dimethyl-4-Oxothieno[2,3-D]Pyrimidin-2-Yl)Thio]-n-(4-Ethylphenyl)- (9Ci) is manufactured under strict quality management systems. Every batch undergoes comprehensive analytical testing, including HPLC for purity, NMR and MS for structural confirmation, and residual solvent analysis. Certificates of Analysis (COA) detailing all specifications and test results are provided to ensure traceability and compliance with your research or development protocols.

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 hygroscopic nature, the container must be kept tightly sealed in a dry environment to prevent moisture absorption, which may affect stability and handling properties. For long-term storage, consider using desiccants.
