The occurrence of 4-(2,4-Dichloro-phenyl)-1-(2-methoxy-phenyl)-1H-imidazole-2-thiol is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4-(2,4-Dichloro-phenyl)-1-(2-methoxy-phenyl)-1H-imidazole-2-thiol (CAS 306956-18-3) is a high-purity analytical reference standard with the molecular formula C16H12Cl2N2OS and a molecular weight of 351.25 g/mol.
4-(2,4-Dichloro-phenyl)-1-(2-methoxy-phenyl)-1H-imidazole-2-thiol (C16H12Cl2N2OS) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, 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).
