Chemical Structure

Hydroxy-PEG2-acid CAS 1334286-77-9 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 178.18 g/mol gives Hydroxy-PEG2-acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Hydroxy-PEG2-acid (CAS 1334286-77-9), molecular formula C7H14O5 and molecular weight 178.18 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C7H14O5, Hydroxy-PEG2-acid contains a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 178.18 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry.

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.
