Chemical Structure

m-PEG5-2-methylacrylate CAS 48074-75-5 chemical structure

Description

CATO supplies m-PEG5-2-methylacrylate (CAS 48074-75-5), a certified reference material (molecular formula C15H28O7, MW 320.38 g/mol) for analytical method development and quality control.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, m-PEG5-2-methylacrylate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 320.38 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.
