Chemical Structure
Description
The occurrence of 3-(2-Chloro-6-fluorophenyl)-5-methyl-N-[3-methyl-4-(propan-2-yl)phenyl]-1,2-oxazole-4-carboxamide is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
3-(2-Chloro-6-fluorophenyl)-5-methyl-N-[3-methyl-4-(propan-2-yl)phenyl]-1,2-oxazole-4-carboxamide (CAS 866150-66-5) is a high-purity analytical reference standard with the molecular formula C21H20ClFN2O2 and a molecular weight of 386.85 g/mol.
3-(2-Chloro-6-fluorophenyl)-5-methyl-N-[3-methyl-4-(propan-2-yl)phenyl]-1,2-oxazole-4-carboxamide (C21H20ClFN2O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, 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).
