Chemical Structure
Description
ethyl (2Z)-2-cyano-3-hydroxy-3-(4-methylphenyl)prop-2-enoate (CAS 91024-54-3) is a high-purity analytical reference standard with the molecular formula C13H13NO3 and a molecular weight of 231.25 g/mol.
Based on its molecular formula C13H13NO3, ethyl (2Z)-2-cyano-3-hydroxy-3-(4-methylphenyl)prop-2-enoate 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 231.25 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.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), ethyl (2Z)-2-cyano-3-hydroxy-3-(4-methylphenyl)prop-2-enoate 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.
