Chemical Structure
Description
The occurrence of N1,N3-Bis(3-nitrophenyl)isophthalamide is closely related to a flavonoid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies N1,N3-Bis(3-nitrophenyl)isophthalamide (CAS 105937-17-5), a certified reference material (molecular formula C20H14N4O6, MW 406.35 g/mol) for analytical method development and quality control.
Based on its molecular formula C20H14N4O6, N1,N3-Bis(3-nitrophenyl)isophthalamide contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 406.35 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
