Chemical Structure
Description
The occurrence of 2-[3-[2-(2,4-dichlorophenyl)hydrazono]-1-(dimethylamino)propylidene]malononitrile is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 2-[3-[2-(2,4-dichlorophenyl)hydrazono]-1-(dimethylamino)propylidene]malononitrile (CAS 339103-09-2), a certified reference material (molecular formula C14H13Cl2N5, MW 322.19 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution, 2-[3-[2-(2,4-dichlorophenyl)hydrazono]-1-(dimethylamino)propylidene]malononitrile is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 322.19 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.
