Chemical Structure

(E)-3-Penten-1-yne CAS 2004-69-5 chemical structure

Description

Owing to an organic framework, (E)-3-Penten-1-yne is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 66.10 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).
