Chemical Structure
Description
The occurrence of 1-(Thiophen-2-yl)cyclobutane-1-carbonitrile is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1-(Thiophen-2-yl)cyclobutane-1-carbonitrile (CAS 28049-65-2) is a high-purity analytical reference standard with the molecular formula C9H9NS and a molecular weight of 163.24 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, 1-(Thiophen-2-yl)cyclobutane-1-carbonitrile is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 163.24 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).
