Chemical Structure

PEG6-(CH2CO2H)2 CAS 77855-76-6 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 354.35 g/mol gives PEG6-(CH2CO2H)2 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

PEG6-(CH2CO2H)2 (CAS 77855-76-6) is a high-purity analytical reference standard with the molecular formula C14H26O10 and a molecular weight of 354.35 g/mol.

The molecular framework of PEG6-(CH2CO2H)2 (C14H26O10) 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.
