General description

4′-Chloroacetanilide is the main impurity present in acetaminophen and has been quantitated by new high-performance liquid chromatography method using a mixed-mode reversed-phase/cation exchange stationary phase.

Application

<ul>
<li><strong>High-performance liquid chromatography (HPLC) method validation:</strong> 4 chloroacetanilide is used as an internal standard for isosorbide dinitrate in the assay of sustained-release tablets or capsules containing nitroglycerin, isosorbide dinitrate, or pentaerythritol tetranitrate by high-performance liquid chromatography (Gelber and Papas, 1983).</li>
