Chemical Structure
Description
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 supplies N-(5-Chloro-4-methyl-2-nitrophenyl)acetamide (CAS 7149-78-2), a certified reference material (molecular formula C9H9ClN2O3, MW 228.63 g/mol) for analytical method development and quality control.
The molecular framework of N-(5-Chloro-4-methyl-2-nitrophenyl)acetamide (C9H9ClN2O3) 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).
CATO manufactures N-(5-Chloro-4-methyl-2-nitrophenyl)acetamide 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.
