Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2,3-Dichloro-4-(ethylsulfonyl)-N-(4-(trifluoromethyl)phenyl)benzamide (CAS 477867-71-3), molecular formula C16H12Cl2F3NO3S and molecular weight 426.24 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2,3-Dichloro-4-(ethylsulfonyl)-N-(4-(trifluoromethyl)phenyl)benzamide (C16H12Cl2F3NO3S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
CATO manufactures 2,3-Dichloro-4-(ethylsulfonyl)-N-(4-(trifluoromethyl)phenyl)benzamide 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.
