10L-751 2-[(5Z)-5-[(4-chlorophenyl)methylidene]-4-oxo-2-sulfanylidene-1,3-thiazolidin-3-yl]-2,3-dihydro-1H-isoindole-1,3-dione 477845-32-2 (CAS 477845-32-2), molecular formula C18H9ClN2O3S2 and molecular weight 400.86 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C18H9ClN2O3S2, 10L-751 2-[(5Z)-5-[(4-chlorophenyl)methylidene]-4-oxo-2-sulfanylidene-1,3-thiazolidin-3-yl]-2,3-dihydro-1H-isoindole-1,3-dione 477845-32-2 contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 400.86 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
