CATO supplies 2,3-Dimethoxy-11-(3-(trifluoromethyl)phenyl)-5,11,12,12a-tetrahydropyrazolo[3',4':4,5]pyrido[2,1-a]isoquinolin-8(6H)-one (CAS 685107-27-1), a certified reference material (molecular formula C23H20F3N3O3, MW 443.42 g/mol) for analytical method development and quality control.
2,3-Dimethoxy-11-(3-(trifluoromethyl)phenyl)-5,11,12,12a-tetrahydropyrazolo[3',4':4,5]pyrido[2,1-a]isoquinolin-8(6H)-one (C23H20F3N3O3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
