Chemical Structure

Boc-PEG4-sulfonic acid CAS 1817735-26-4 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 386.46 g/mol gives Boc-PEG4-sulfonic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Boc-PEG4-sulfonic acid (CAS 1817735-26-4), a certified reference material (molecular formula C15H30O9S, MW 386.46 g/mol) for analytical method development and quality control.

Boc-PEG4-sulfonic acid (C15H30O9S) contains a sulfone group, 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.
