Chemical Structure
Description
CATO supplies N-(4-Amino-5-chloro-2-hydroxyphenyl)-3,4-dichlorobenzamide (CAS 95709-82-3), a certified reference material (molecular formula C13H9Cl3N2O2, MW 331.58 g/mol) for analytical method development and quality control.
The molecular framework of N-(4-Amino-5-chloro-2-hydroxyphenyl)-3,4-dichlorobenzamide (C13H9Cl3N2O2) 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 its high hydrophobicity (logP), 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).
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 N-(4-Amino-5-chloro-2-hydroxyphenyl)-3,4-dichlorobenzamide 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.
