Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 272.13 g/mol gives Ethyl 2-cyano-3-(2,3-dichlorophenyl)propanoate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Ethyl 2-cyano-3-(2,3-dichlorophenyl)propanoate (CAS 39959-98-3) is a high-purity analytical reference standard with the molecular formula C12H11Cl2NO2 and a molecular weight of 272.13 g/mol.
Ethyl 2-cyano-3-(2,3-dichlorophenyl)propanoate (C12H11Cl2NO2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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 2-cyano-3-(2,3-dichlorophenyl)propanoate 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.
