Compared with other compounds in its class, the molecular weight of 262.71 g/mol gives 3-((2-Chlorobenzyl)sulfonyl)propanoic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 3-((2-Chlorobenzyl)sulfonyl)propanoic acid (CAS 440649-47-8), a certified reference material (molecular formula C10H11ClO4S, MW 262.71 g/mol) for analytical method development and quality control.
3-((2-Chlorobenzyl)sulfonyl)propanoic acid (C10H11ClO4S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. It is notably hygroscopic, 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. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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 3-((2-Chlorobenzyl)sulfonyl)propanoic acid 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.
