Chemical Structure
Description
2-Chloro-N-(2-chloro-4-nitrophenyl)acetamide (CAS 34004-41-6) is a high-purity analytical reference standard with the molecular formula C8H6Cl2N2O3 and a molecular weight of 249.05 g/mol.
2-Chloro-N-(2-chloro-4-nitrophenyl)acetamide (C8H6Cl2N2O3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 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. 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 2-Chloro-N-(2-chloro-4-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.
