{4-[(4-chlorophenyl)sulfanyl]-3-nitrophenyl}methyl N-cyclohexylcarbamate (CAS 320424-17-7) is a high-purity analytical reference standard with the molecular formula C20H21ClN2O4S and a molecular weight of 420.91 g/mol.
{4-[(4-chlorophenyl)sulfanyl]-3-nitrophenyl}methyl N-cyclohexylcarbamate (C20H21ClN2O4S) contains a flavonoid 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.
