The occurrence of 2-(1-Chloroethyl)-5-(4-chlorophenyl)-4-methyl-1,3-oxazole is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-(1-Chloroethyl)-5-(4-chlorophenyl)-4-methyl-1,3-oxazole (CAS 1152541-88-2), molecular formula C12H11Cl2NO and molecular weight 256.13 g/mol, is a CATO reference standard with documented purity and traceability.
2-(1-Chloroethyl)-5-(4-chlorophenyl)-4-methyl-1,3-oxazole (C12H11Cl2NO) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; 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).
