CATO supplies 2,2-[Methylenebis[(2-chloro-4,1-phenylene)iminocarbonylimino-4,1-phenyleneoxy]]bis[2-methylpropanoic acid] (CAS 245075-84-7), a certified reference material (molecular formula C35H34Cl2N4O8, MW 709.57 g/mol) for analytical method development and quality control.
2,2-[Methylenebis[(2-chloro-4,1-phenylene)iminocarbonylimino-4,1-phenyleneoxy]]bis[2-methylpropanoic acid] (C35H34Cl2N4O8) 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
