Chemical Structure
Description
The occurrence of 2,4-Dichloro-1-(methylsulfonyl)benzene is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2,4-Dichloro-1-(methylsulfonyl)benzene (CAS 85901-48-0), molecular formula C7H6Cl2O2S and molecular weight 225.09 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2,4-Dichloro-1-(methylsulfonyl)benzene (C7H6Cl2O2S) 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
