Ethyl 4-(3-cyanophenyl)-4-oxobutanoate CAS 951885-57-7

Description

Compared with other compounds in its class, the molecular weight of 231.25 g/mol gives Ethyl 4-(3-cyanophenyl)-4-oxobutanoate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Ethyl 4-(3-cyanophenyl)-4-oxobutanoate (CAS 951885-57-7), molecular formula C13H13NO3 and molecular weight 231.25 g/mol, is a CATO reference standard with documented purity and traceability.

Ethyl 4-(3-cyanophenyl)-4-oxobutanoate (C13H13NO3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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 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 4-(3-cyanophenyl)-4-oxobutanoate 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.
