Hexanedioic acid, polymer with 1,4-cyclohexanedimethanol and 1,2-ethanediol CAS 81972-46-5

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Hexanedioic acid, polymer with 1,4-cyclohexanedimethanol and 1,2-ethanediol.

Hexanedioic acid, polymer with 1,4-cyclohexanedimethanol and 1,2-ethanediol (CAS 81972-46-5), molecular formula C6H10O4C8H16O2C2H6O2 and molecular weight 352.42 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Hexanedioic acid, polymer with 1,4-cyclohexanedimethanol and 1,2-ethanediol (C6H10O4C8H16O2C2H6O2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development.

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.
