Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 280.15 g/mol gives N-(2,5-Dichlorophenyl)-4-methylbenzamide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies N-(2,5-Dichlorophenyl)-4-methylbenzamide (CAS 90665-33-1), a certified reference material (molecular formula C14H11Cl2NO, MW 280.15 g/mol) for analytical method development and quality control.
N-(2,5-Dichlorophenyl)-4-methylbenzamide (C14H11Cl2NO) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; 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).
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.
