2-[2-(4-fluorophenyl)-1,3-oxazol-4-yl]acetic acid CAS 22091-43-6

Description

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.

CATO supplies 2-[2-(4-fluorophenyl)-1,3-oxazol-4-yl]acetic acid (CAS 22091-43-6), a certified reference material (molecular formula C11H8FNO3, MW 221.18 g/mol) for analytical method development and quality control.

The molecular framework of 2-[2-(4-fluorophenyl)-1,3-oxazol-4-yl]acetic acid (C11H8FNO3) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. 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.
