Chemical Structure

m-PEG7-Boc CAS 874208-90-9 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 424.53 g/mol gives m-PEG7-Boc distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies m-PEG7-Boc (CAS 874208-90-9), a certified reference material (molecular formula C20H40O9, MW 424.53 g/mol) for analytical method development and quality control.

m-PEG7-Boc (C20H40O9) contains a carboxylic acid group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions.

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.
