Chemical Structure

m-PEG16-SH CAS 874820-38-9 chemical structure

Description

The occurrence of m-PEG16-SH is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

m-PEG16-SH (CAS 874820-38-9) is a high-purity analytical reference standard with the molecular formula C33H68O16S and a molecular weight of 752.95 g/mol.

m-PEG16-SH (C33H68O16S) 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.
