Chemical Structure

2-Chloro-N-[4-nitro-2-(trifluoromethyl)phenyl]acetamide CAS 379255-51-3 chemical structure

Description

CATO manufactures 2-Chloro-N-[4-nitro-2-(trifluoromethyl)phenyl]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.

2-Chloro-N-[4-nitro-2-(trifluoromethyl)phenyl]acetamide (CAS 379255-51-3) is a high-purity analytical reference standard with the molecular formula C9H6ClF3N2O3 and a molecular weight of 282.60 g/mol.

2-Chloro-N-[4-nitro-2-(trifluoromethyl)phenyl]acetamide (C9H6ClF3N2O3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
