4-[3-(2,6-Dichlorophenyl)-5-methyl-1,2-oxazole-4-carbonyl]-N-(2-methylbutan-2-yl)-1H-pyrrole-2-carboxamide (CAS 478064-56-1) is a high-purity analytical reference standard with the molecular formula C21H21Cl2N3O3 and a molecular weight of 434.32 g/mol.
4-[3-(2,6-Dichlorophenyl)-5-methyl-1,2-oxazole-4-carbonyl]-N-(2-methylbutan-2-yl)-1H-pyrrole-2-carboxamide (C21H21Cl2N3O3) 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. 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.
