Chemical Structure

Propargyl-PEG8-OH CAS 1351556-81-4 chemical structure

Description

The occurrence of Propargyl-PEG8-OH is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Propargyl-PEG8-OH (CAS 1351556-81-4), a certified reference material (molecular formula C19H36O9, MW 408.48 g/mol) for analytical method development and quality control.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, Propargyl-PEG8-OH is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 408.48 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

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.
