Description
Compared with other compounds in its class, the molecular weight of 319.12 g/mol gives 8-Iodo-2-(methylthio)pyrido[4,3-d]pyrimidin-5(6H)-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
8-Iodo-2-(methylthio)pyrido[4,3-d]pyrimidin-5(6H)-one (CAS 1562987-77-2), molecular formula C8H6IN3OS and molecular weight 319.12 g/mol, is a CATO reference standard with documented purity and traceability.
8-Iodo-2-(methylthio)pyrido[4,3-d]pyrimidin-5(6H)-one (C8H6IN3OS) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, iodine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
