Pentanedioic acid, 1,5-dimethyl ester, polymer with N1-(2-aminoethyl)-1,2-ethanediamine, N1,N1-dimethyl-1,3-propanediamine and 1,1'-oxybis[2-chloroethane] CAS 61470-87-9

Description

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.

CATO supplies Pentanedioic acid, 1,5-dimethyl ester, polymer with N1-(2-aminoethyl)-1,2-ethanediamine, N1,N1-dimethyl-1,3-propanediamine and 1,1'-oxybis[2-chloroethane] (CAS 61470-87-9), a certified reference material (molecular formula C7H12O4C4H8Cl2OC4H13N3C5H14N2, MW 508.53 g/mol) for analytical method development and quality control.

The molecular framework of Pentanedioic acid, 1,5-dimethyl ester, polymer with N1-(2-aminoethyl)-1,2-ethanediamine, N1,N1-dimethyl-1,3-propanediamine and 1,1'-oxybis[2-chloroethane] (C7H12O4C4H8Cl2OC4H13N3C5H14N2) is characterized by an amide group, a carboxylic acid 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. 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.
