Chemical Structure

Ethyl but-3-ynoate CAS 53841-07-9 chemical structure

Description

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, Ethyl but-3-ynoate is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 112.13 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

CATO supplies Ethyl but-3-ynoate (CAS 53841-07-9), a certified reference material (molecular formula C6H8O2, MW 112.13 g/mol) for analytical method development and quality control.
