5-(2-Chlorophenyl)-N-(2-nitrophenyl)furan-2-carboxamide CAS 199458-85-0

Description

The occurrence of 5-(2-Chlorophenyl)-N-(2-nitrophenyl)furan-2-carboxamide is closely related to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

5-(2-Chlorophenyl)-N-(2-nitrophenyl)furan-2-carboxamide (CAS 199458-85-0) is a high-purity analytical reference standard with the molecular formula C17H11ClN2O4 and a molecular weight of 342.73 g/mol.

5-(2-Chlorophenyl)-N-(2-nitrophenyl)furan-2-carboxamide (C17H11ClN2O4) contains a flavonoid core, 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.

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.
