2-(5-Methyl-3-oxo-2,3-dihydro-1H-inden-1-ylidene)malononitrile CAS 2047352-75-8

Description

The occurrence of 2-(5-Methyl-3-oxo-2,3-dihydro-1H-inden-1-ylidene)malononitrile is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2-(5-Methyl-3-oxo-2,3-dihydro-1H-inden-1-ylidene)malononitrile (CAS 2047352-75-8), molecular formula C13H8N2O and molecular weight 208.22 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-(5-Methyl-3-oxo-2,3-dihydro-1H-inden-1-ylidene)malononitrile is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 208.22 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).

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.
