Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 326.13 g/mol gives 1-(4-Chloro-3-nitrophenyl)-3-(3-chlorophenyl)urea distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 1-(4-Chloro-3-nitrophenyl)-3-(3-chlorophenyl)urea (CAS 574724-12-2), a certified reference material (molecular formula C13H9Cl2N3O3, MW 326.13 g/mol) for analytical method development and quality control.
1-(4-Chloro-3-nitrophenyl)-3-(3-chlorophenyl)urea (C13H9Cl2N3O3) 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).
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.
