Quality Control

Our 2-Mercapto-3-Phenylpyrido[2,3-D]Pyrimidin-4(3H)-One is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity for research and production use. All products undergo rigorous analytical testing, including HPLC, NMR, and mass spectrometry, to confirm identity and purity. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with each shipment to support your quality assurance and regulatory documentation needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its sensitivity to oxidation, long-term storage under an inert atmosphere (e.g., nitrogen or argon) is recommended for optimal stability.
