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.
(4-Chlorosulfonyl-phenyl)-acetic acid ethyl ester (CAS 87202-52-6) is a high-purity analytical reference standard with the molecular formula C10H11ClO4S and a molecular weight of 262.71 g/mol.
(4-Chlorosulfonyl-phenyl)-acetic acid ethyl ester (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.
CATO manufactures (4-Chlorosulfonyl-phenyl)-acetic acid ethyl ester 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.
