Chemical Structure
Description
2-Cyano-3-phenyl-2-butenoic acid ethyl ester (cis-trans isomer mixture) (CAS 18300-89-5) is a high-purity analytical reference standard with the molecular formula C13H19NO2 and a molecular weight of 221.30 g/mol.
Based on its molecular formula C13H19NO2, 2-Cyano-3-phenyl-2-butenoic acid ethyl ester (cis-trans isomer mixture) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 221.30 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
As a certified reference material (CRM), 2-Cyano-3-phenyl-2-butenoic acid ethyl ester (cis-trans isomer mixture) 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.
