Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 6-(2,6-Dichlorophenyl)-8-methyl-2-((3-(methylthio)phenyl)amino)pyrido[2,3-d]pyrimidin-7(8H)-one.
6-(2,6-Dichlorophenyl)-8-methyl-2-((3-(methylthio)phenyl)amino)pyrido[2,3-d]pyrimidin-7(8H)-one (CAS 260415-63-2), molecular formula C21H16Cl2N4OS and molecular weight 443.35 g/mol, is a CATO reference standard with documented purity and traceability.
6-(2,6-Dichlorophenyl)-8-methyl-2-((3-(methylthio)phenyl)amino)pyrido[2,3-d]pyrimidin-7(8H)-one (C21H16Cl2N4OS) contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
