Chemical Structure

Ethyl 3-phenyl-3-(phenylsulfonyl)propanoate CAS 60156-18-5 chemical structure

Description

The molecular framework of Ethyl 3-phenyl-3-(phenylsulfonyl)propanoate (C17H18O4S) is characterized by a flavonoid core, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

Ethyl 3-phenyl-3-(phenylsulfonyl)propanoate (CAS 60156-18-5) is a high-purity analytical reference standard with the molecular formula C17H18O4S and a molecular weight of 318.39 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
