Chemical Structure
Description
The molecular framework of 4-Chloro-3-(3-(3-chlorophenyl)ureido)benzoic acid (C14H10Cl2N2O3) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing 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).
4-Chloro-3-(3-(3-chlorophenyl)ureido)benzoic acid (CAS 923738-03-8) is a high-purity analytical reference standard with the molecular formula C14H10Cl2N2O3 and a molecular weight of 325.15 g/mol.
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 4-Chloro-3-(3-(3-chlorophenyl)ureido)benzoic 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.
