4-methyl-2-(methylsulfanyl)-7H,8H-pyrido[2,3-d]pyrimidin-7-one (CAS 846036-77-9), molecular formula C9H17N3OS and molecular weight 215.32 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 4-methyl-2-(methylsulfanyl)-7H,8H-pyrido[2,3-d]pyrimidin-7-one (C9H17N3OS) is characterized by an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
