Methyl 3-chloro-4-(chlorosulfonyl)benzoate CAS 874830-93-0

Description

Compared with other compounds in its class, the molecular weight of 269.10 g/mol gives Methyl 3-chloro-4-(chlorosulfonyl)benzoate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Methyl 3-chloro-4-(chlorosulfonyl)benzoate (CAS 874830-93-0), molecular formula C8H6Cl2O4S and molecular weight 269.10 g/mol, is a CATO reference standard with documented purity and traceability.

Methyl 3-chloro-4-(chlorosulfonyl)benzoate (C8H6Cl2O4S) 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, 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).

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 Methyl 3-chloro-4-(chlorosulfonyl)benzoate 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.
