4-(Ethylthio)-3-iodobenzophenone (CAS 951885-53-3) is a high-purity analytical reference standard with the molecular formula C15H13IOS and a molecular weight of 368.23 g/mol.
4-(Ethylthio)-3-iodobenzophenone (C15H13IOS) contains sulfur-containing functionality, a hydroxyl group, an ether linkage, iodine substitution, a polycyclic aromatic system. 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.
