Chemical Structure

cis-5-Methyl-4,4-diphenyl-1,3,2-dioxathiolane 2-oxide CAS 51226-54-1 chemical structure

Description

The molecular framework of cis-5-Methyl-4,4-diphenyl-1,3,2-dioxathiolane 2-oxide (C15H14O3S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. 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 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).

cis-5-Methyl-4,4-diphenyl-1,3,2-dioxathiolane 2-oxide (CAS 51226-54-1), molecular formula C15H14O3S and molecular weight 274.33 g/mol, is a CATO reference standard with documented purity and traceability.

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.
