Chemical Structure

1H-Pyrrole-2,5-dione, 1,1'-(methylenedi-4,1-phenylene)bis-, polymer with 2,4-bis[(4-aminophenyl)methyl]benzenamine and 4,4'-methylenebis[benzenamine] CAS 102900-05-0 chemical structure

Description

The occurrence of 1H-Pyrrole-2,5-dione, 1,1'-(methylenedi-4,1-phenylene)bis-, polymer with 2,4-bis[(4-aminophenyl)methyl]benzenamine and 4,4'-methylenebis[benzenamine] is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 1H-Pyrrole-2,5-dione, 1,1'-(methylenedi-4,1-phenylene)bis-, polymer with 2,4-bis[(4-aminophenyl)methyl]benzenamine and 4,4'-methylenebis[benzenamine] (CAS 102900-05-0), a certified reference material (molecular formula C21H14N2O4C20H21N3C13H14N2, MW 860.03 g/mol) for analytical method development and quality control.

1H-Pyrrole-2,5-dione, 1,1'-(methylenedi-4,1-phenylene)bis-, polymer with 2,4-bis[(4-aminophenyl)methyl]benzenamine and 4,4'-methylenebis[benzenamine] (C21H14N2O4C20H21N3C13H14N2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
