Chemical Structure

5-Phenylfuran-2(3H)-one CAS 1955-39-1 chemical structure

Description

CATO supplies 5-Phenylfuran-2(3H)-one (CAS 1955-39-1), a certified reference material (molecular formula C11H20S4, MW 280.54 g/mol) for analytical method development and quality control.

Structurally, 5-Phenylfuran-2(3H)-one (C11H20S4) contains sulfur-containing functionality. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 280.54 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
