Chemical Structure
Description
The molecular framework of 1172749-36-8 2-(Methylthio)-5,6,7,8-tetrahydropyrido-[4,3-d]pyrimidin-4(3H)-one 9911AC C8H11N3OS (C8H11N3OS) is characterized by a nitrogen-containing heterocyclic scaffold, 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
