2-(3,4-Dichlorophenyl)sulfanylbenzoic acid CAS 50900-45-3

Description

Compared with other compounds in its class, the molecular weight of 299.17 g/mol gives 2-(3,4-Dichlorophenyl)sulfanylbenzoic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-(3,4-Dichlorophenyl)sulfanylbenzoic acid (CAS 50900-45-3), molecular formula C13H8Cl2O2S and molecular weight 299.17 g/mol, is a CATO reference standard with documented purity and traceability.

2-(3,4-Dichlorophenyl)sulfanylbenzoic acid (C13H8Cl2O2S) 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, 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 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.

As a certified reference material (CRM), 2-(3,4-Dichlorophenyl)sulfanylbenzoic acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
