Chemical Structure
Description
(E)-2-(2-Fluorocyclopentylidene)acetonitrile (CAS 2171492-90-1) is a high-purity analytical reference standard with the molecular formula C7H8FN and a molecular weight of 125.14 g/mol.
Structurally, (E)-2-(2-Fluorocyclopentylidene)acetonitrile (C7H8FN) contains a nitrile group, fluorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 125.14 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
