3,4-Dichloro-N-(3-cyano-4-(p-tolylthio)phenyl)benzamide (CAS 306980-44-9), molecular formula C21H14Cl2N2OS and molecular weight 413.32 g/mol, is a CATO reference standard with documented purity and traceability.
3,4-Dichloro-N-(3-cyano-4-(p-tolylthio)phenyl)benzamide (C21H14Cl2N2OS) contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; 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.
