(5e)-2-mercapto-5-(2-methoxybenzylidene)-3-phenyl-3,5-dihydro-4h-imidazol-4-one 13109-89-2 (CAS 13109-89-2) is a high-purity analytical reference standard with the molecular formula C17H14N2O2S and a molecular weight of 310.37 g/mol.
(5e)-2-mercapto-5-(2-methoxybenzylidene)-3-phenyl-3,5-dihydro-4h-imidazol-4-one 13109-89-2 (C17H14N2O2S) contains a steroid core, 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
