Chemical Structure
Description
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, 2-(4-Cyanobenzylidene)malononitrile is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 179.18 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
2-(4-Cyanobenzylidene)malononitrile (CAS 36937-92-5), molecular formula C11H5N3 and molecular weight 179.18 g/mol, is a CATO reference standard with documented purity and traceability.
