Chemical Structure

4'-Methyl-[1,1'-biphenyl]-2-sulfonylchloride CAS 173253-46-8 chemical structure

Description

CATO manufactures 4'-Methyl-[1,1'-biphenyl]-2-sulfonylchloride 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.

CATO supplies 4'-Methyl-[1,1'-biphenyl]-2-sulfonylchloride (CAS 173253-46-8), a certified reference material (molecular formula C13H11ClO2S, MW 266.74 g/mol) for analytical method development and quality control.

4'-Methyl-[1,1'-biphenyl]-2-sulfonylchloride (C13H11ClO2S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring 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.
