Chemical Structure
Description
The occurrence of 2-Aminothiophene-3-carbonitrile is closely related to a nitrile group, sulfur-containing functionality in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-Aminothiophene-3-carbonitrile (CAS 4651-82-5) is a high-purity analytical reference standard with the molecular formula C5H4N2S and a molecular weight of 124.16 g/mol.
Structurally, 2-Aminothiophene-3-carbonitrile (C5H4N2S) contains a nitrile group, sulfur-containing functionality. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 124.16 g/mol, it falls into the low-molecular-weight range. 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).
