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.
2-(3,4-Dichloro-phenyl)-ethanesulfonyl chloride (CAS 1161945-63-6) is a high-purity analytical reference standard with the molecular formula C8H7Cl3O2S and a molecular weight of 273.56 g/mol.
2-(3,4-Dichloro-phenyl)-ethanesulfonyl chloride (C8H7Cl3O2S) 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, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO manufactures 2-(3,4-Dichloro-phenyl)-ethanesulfonyl chloride 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.
