Chemical Structure
Description
4-(3-Methoxy-4-methylphenyl)thiazole-2-carboxylic acid (C12H11NO3S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
4-(3-Methoxy-4-methylphenyl)thiazole-2-carboxylic acid (CAS 886367-20-0) is a high-purity analytical reference standard with the molecular formula C12H11NO3S and a molecular weight of 249.29 g/mol.
