Chemical Structure
Description
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.
Methyl 3-(3-(chlorosulfonyl)phenyl)propanoate (CAS 866787-22-6), molecular formula C10H11ClO4S and molecular weight 262.71 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Methyl 3-(3-(chlorosulfonyl)phenyl)propanoate (C10H11ClO4S) 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.
CATO manufactures Methyl 3-(3-(chlorosulfonyl)phenyl)propanoate 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.
