Quality Control

Our Ethyl 5-Hydroxy-8-Isopentyl-2-(Methylthio)-7-Oxo-7,8-Dihydropyrido[2,3-D]Pyrimidine-6-Carboxylate is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation (IR, NMR), to ensure it meets the stringent requirements for pharmaceutical R&D applications. Certificates of Analysis (COA) detailing all specifications are provided with every shipment.

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.
