(5-(1,3-Dioxolan-2-yl)thiophen-2-yl)(4-ethylphenyl)methanone CAS 898778-46-6

Description

The occurrence of (5-(1,3-Dioxolan-2-yl)thiophen-2-yl)(4-ethylphenyl)methanone is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies (5-(1,3-Dioxolan-2-yl)thiophen-2-yl)(4-ethylphenyl)methanone (CAS 898778-46-6), a certified reference material (molecular formula C16H16O3S, MW 288.36 g/mol) for analytical method development and quality control.

The molecular framework of (5-(1,3-Dioxolan-2-yl)thiophen-2-yl)(4-ethylphenyl)methanone (C16H16O3S) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
