<h3>Overview</h3>
<p>Ibuprofen Impurity D (EP) is a critical reference standard for the quality control of non-steroidal anti-inflammatory drugs. Synthesized via specific oxidation pathways, it serves as an identification marker in pharmaceutical assays. The compound features the molecular formula <strong>C<sub>14</sub>H<sub>20</sub>O<sub>2</sub></strong> and carries the CAS number <strong>57849-60-4</strong>.</p>
<h3>Application</h3>
<ul>
<li><strong>Quality Assurance:</strong> Used by API manufacturers to validate synthesis purity against EP monographs.</li>
<li><strong>R&D Analysis:</strong> Employed in stability studies to monitor degradation products during storage.</li>
<li><strong>Regulatory Compliance:</strong> Essential for submitting impurity profiles to EMA and FDA authorities.</li>
</ul>
<h3>Precautions</h3>
<p>Store under inert atmosphere at 2–8°C to prevent degradation. Personnel must utilize appropriate PPE including gloves and goggles due to potential irritant properties. Strictly avoid ingestion or inhalation during handling procedures.</p>
