Chemical Structure
Description
(2E)-2-(4-Chlorophenyl)-3-[(2-methylphenyl)amino]prop-2-enenitrile (CAS 338403-04-6) is a high-purity analytical reference standard with the molecular formula C16H13ClN2 and a molecular weight of 268.74 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution, (2E)-2-(4-Chlorophenyl)-3-[(2-methylphenyl)amino]prop-2-enenitrile is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 268.74 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.
As a certified reference material (CRM), (2E)-2-(4-Chlorophenyl)-3-[(2-methylphenyl)amino]prop-2-enenitrile meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
