Chemical Structure
Description
4-((2,5-Dichlorophenyl)sulfonyl)butan-2-one (CAS 336195-37-0), molecular formula C10H10Cl2O3S and molecular weight 281.16 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-((2,5-Dichlorophenyl)sulfonyl)butan-2-one (C10H10Cl2O3S) 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 its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 4-((2,5-Dichlorophenyl)sulfonyl)butan-2-one 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.
