Quality Control
Our 4-Methyl-2-Thioxo-6-(3,4,5-Trimethoxyphenyl)-3,6-Dihydro-1H-Pyrimidine-5-Carboxylic Acid Ethyl Ester is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and mass spectrometry, to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing all specifications are provided and can be tailored to meet specific client requirements for research or cGMP-grade material.
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 (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture. Keep away from incompatible materials.
