Description

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.

Ethyl 4-(4-(ethylthio)phenyl)-4-oxobutanoate (CAS 7028-71-9), molecular formula C14H18O3S and molecular weight 266.36 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C14H18O3S, Ethyl 4-(4-(ethylthio)phenyl)-4-oxobutanoate contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 266.36 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).

As a certified reference material (CRM), Ethyl 4-(4-(ethylthio)phenyl)-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.
