Chemical Structure
Description
The occurrence of m-PEG3-S-PEG4-propargyl 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.
CATO supplies m-PEG3-S-PEG4-propargyl (CAS 2055040-85-0), a certified reference material (molecular formula C18H34O7S, MW 394.52 g/mol) for analytical method development and quality control.
Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, m-PEG3-S-PEG4-propargyl is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 394.52 g/mol — guide the selection of appropriate sample preparation and analytical techniques.
