Chemical Structure
Description
The occurrence of cis-1-(3-ethynylcyclobutyl)ethanone is closely related to a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
cis-1-(3-ethynylcyclobutyl)ethanone (CAS 42809-44-9) is a high-purity analytical reference standard with the molecular formula C8H10O and a molecular weight of 122.16 g/mol.
cis-1-(3-ethynylcyclobutyl)ethanone (C8H10O) contains a hydroxyl group, an ether linkage, an aromatic ring system. Its physicochemical properties are representative of its class; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).
