Chemical Structure
Description
The molecular framework of 1,4-Benzenedicarboxylic acid, polymer with hexahydro-2H-azepin-2-one and 4,4'-methylenebis[cyclohexanamine] (C13H26N2C8H6O4C6H11NO) is characterized by a steroid 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
1,4-Benzenedicarboxylic acid, polymer with hexahydro-2H-azepin-2-one and 4,4'-methylenebis[cyclohexanamine] (CAS 42553-22-0), molecular formula C13H26N2C8H6O4C6H11NO and molecular weight 489.66 g/mol, is a CATO reference standard with documented purity and traceability.
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.
