Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 191.66 g/mol gives 2-Chloro-4-(4-cyanophenyl)-1-butene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-Chloro-4-(4-cyanophenyl)-1-butene (CAS 731772-75-1) is a high-purity analytical reference standard with the molecular formula C11H10ClN and a molecular weight of 191.66 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution, 2-Chloro-4-(4-cyanophenyl)-1-butene is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 191.66 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), 2-Chloro-4-(4-cyanophenyl)-1-butene 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.
