2-(4-benzoyl-3-cyano-5-hydroxy-5-methyl-1,5-dihydro-2H-pyrrol-2-yliden)malononitrile CAS 42046-43-5 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 290.28 g/mol gives 2-(4-benzoyl-3-cyano-5-hydroxy-5-methyl-1,5-dihydro-2H-pyrrol-2-yliden)malononitrile distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-(4-benzoyl-3-cyano-5-hydroxy-5-methyl-1,5-dihydro-2H-pyrrol-2-yliden)malononitrile (CAS 42046-43-5), molecular formula C16H10N4O2 and molecular weight 290.28 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 2-(4-benzoyl-3-cyano-5-hydroxy-5-methyl-1,5-dihydro-2H-pyrrol-2-yliden)malononitrile is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 290.28 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).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
