CATO supplies 1,6-Dihydro-4-hydroxy-1-[2-(1H-indol-3-yl)ethyl]-6-oxo-5-(phenylmethyl)-3-pyridinecarboxaldehyde 3-[O-[(3-chlorophenyl)methyl]oxime] (CAS 477888-13-4), a certified reference material (molecular formula C30H26ClN3O3, MW 512.00 g/mol) for analytical method development and quality control.
1,6-Dihydro-4-hydroxy-1-[2-(1H-indol-3-yl)ethyl]-6-oxo-5-(phenylmethyl)-3-pyridinecarboxaldehyde 3-[O-[(3-chlorophenyl)methyl]oxime] (C30H26ClN3O3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine 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.
