Chemical Structure

Ethyl 2-tosylpropanoate CAS 95314-82-2 chemical structure

Description

Based on its molecular formula C12H16O4S, Ethyl 2-tosylpropanoate 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 256.32 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.

Ethyl 2-tosylpropanoate (CAS 95314-82-2) is a high-purity analytical reference standard with the molecular formula C12H16O4S and a molecular weight of 256.32 g/mol.

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.
