Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-(4-(4-Fluorophenyl)-2-(4-(methylsulfonyl)phenyl)-1H-imidazol-5-yl)pyridine.
4-(4-(4-Fluorophenyl)-2-(4-(methylsulfonyl)phenyl)-1H-imidazol-5-yl)pyridine (CAS 152121-46-5), molecular formula C21H16FN3O2S and molecular weight 393.43 g/mol, is a CATO reference standard with documented purity and traceability.
4-(4-(4-Fluorophenyl)-2-(4-(methylsulfonyl)phenyl)-1H-imidazol-5-yl)pyridine (C21H16FN3O2S) contains a steroid core, an amide group, a sulfone 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. 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.
