Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2-(Methylthio)-7-(trifluoromethyl)pyrido[2,3-d]pyrimidine (CAS 2529569-27-3) is a high-purity analytical reference standard with the molecular formula C9H6F3N3S and a molecular weight of 245.22 g/mol.
2-(Methylthio)-7-(trifluoromethyl)pyrido[2,3-d]pyrimidine (C9H6F3N3S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, fluorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
