(E)-1-[2-(4-Chlorophenyl)-4-methyl-1,3-thiazol-5-yl]-3-(2-nitrophenyl)-2-propen-1-one (CAS 1211932-77-2), molecular formula C19H13ClN2O3S and molecular weight 384.84 g/mol, is a CATO reference standard with documented purity and traceability.
(E)-1-[2-(4-Chlorophenyl)-4-methyl-1,3-thiazol-5-yl]-3-(2-nitrophenyl)-2-propen-1-one (C19H13ClN2O3S) contains a steroid core, an amide group, a sulfone 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.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
