Chemical Structure
Description
The occurrence of 1-(3,4-Dichlorophenyl)-2-(4-methylbenzenesulfonyl)ethan-1-ol is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1-(3,4-Dichlorophenyl)-2-(4-methylbenzenesulfonyl)ethan-1-ol (CAS 477867-77-9), molecular formula C15H14Cl2O3S and molecular weight 345.24 g/mol, is a CATO reference standard with documented purity and traceability.
1-(3,4-Dichlorophenyl)-2-(4-methylbenzenesulfonyl)ethan-1-ol (C15H14Cl2O3S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic system. Halogen substitution raises its density and boiling point, 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. 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.
CATO manufactures 1-(3,4-Dichlorophenyl)-2-(4-methylbenzenesulfonyl)ethan-1-ol under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
