Chemical Structure
Description
The molecular framework of 4-(2-methylpropane-2-sulfonyl)benzene-1-sulfonyl chloride (C10H13ClO4S2) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
4-(2-methylpropane-2-sulfonyl)benzene-1-sulfonyl chloride (CAS 1601749-56-7) is a high-purity analytical reference standard with the molecular formula C10H13ClO4S2 and a molecular weight of 296.79 g/mol.
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.
