Chemical Structure

2H-Azepin-2-one, hexahydro-, polymer with 2,4-diisocyanato-1-methylbenzene and 2,2'-(methylimino)bis[ethanol] CAS 72259-86-0 chemical structure

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 2H-Azepin-2-one, hexahydro-, polymer with 2,4-diisocyanato-1-methylbenzene and 2,2'-(methylimino)bis[ethanol] (CAS 72259-86-0), a certified reference material (molecular formula C9H6N2O2C5H13NO2C6H11NO, MW 406.48 g/mol) for analytical method development and quality control.

The molecular framework of 2H-Azepin-2-one, hexahydro-, polymer with 2,4-diisocyanato-1-methylbenzene and 2,2'-(methylimino)bis[ethanol] (C9H6N2O2C5H13NO2C6H11NO) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
