Chemical Structure
Description
2-Chloro-N-(4-chloro-2-nitrophenyl)acetamide (CAS 40930-49-2), molecular formula C8H6Cl2N2O3 and molecular weight 249.05 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C8H6Cl2N2O3, 2-Chloro-N-(4-chloro-2-nitrophenyl)acetamide contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 249.05 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
