Chemical Structure

HO-PEG6-CH2COOH CAS 120394-66-3 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 HO-PEG6-CH2COOH (CAS 120394-66-3), a certified reference material (molecular formula C14H28O9, MW 340.37 g/mol) for analytical method development and quality control.

The molecular framework of HO-PEG6-CH2COOH (C14H28O9) 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.

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.
