1,3-Benzenedicarboxylic acid, polymer with N1-(2-aminoethyl)-1,2-ethanediamine and 2-(chloromethyl)oxirane (CAS 61981-24-6) is a high-purity analytical reference standard with the molecular formula C8H6O4C4H13N3C3H5ClO and a molecular weight of 361.82 g/mol.
The molecular framework of 1,3-Benzenedicarboxylic acid, polymer with N1-(2-aminoethyl)-1,2-ethanediamine and 2-(chloromethyl)oxirane (C8H6O4C4H13N3C3H5ClO) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
