Description

Compared with other compounds in its class, the molecular weight of 251.13 g/mol gives 2-((2,4-Dichloro-5-methylphenyl)thio)acetic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-((2,4-Dichloro-5-methylphenyl)thio)acetic acid (CAS 71735-21-2), molecular formula C9H8Cl2O2S and molecular weight 251.13 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2-((2,4-Dichloro-5-methylphenyl)thio)acetic acid (C9H8Cl2O2S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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 2-((2,4-Dichloro-5-methylphenyl)thio)acetic 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.
