2-(3-Methylbenzylidene)malononitrile CAS 15728-26-4

Description

Compared with other compounds in its class, the molecular weight of 168.19 g/mol gives 2-(3-Methylbenzylidene)malononitrile distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-(3-Methylbenzylidene)malononitrile (CAS 15728-26-4), molecular formula C11H8N2 and molecular weight 168.19 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, 2-(3-Methylbenzylidene)malononitrile is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 168.19 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
