<h3>Overview</h3>
<p><strong>Metronidazole EP Impurity D</strong> is a critical reference standard used in pharmaceutical quality control to monitor degradation pathways of the antibiotic metronidazole. Synthesized via nitroimidazole coupling reactions, it serves as an essential marker for HPLC method validation. Molecular formula: <strong>C6H9N3O2</strong>; CAS No.: <strong>1075-18-5</strong>.</p>
<h3>Application</h3>
<ul>
<li>Pharmaceutical R&D for establishing impurity profiling protocols.</li>
<li>Quality assurance testing in API manufacturing facilities.</li>
<li>Regulatory compliance documentation for FDA and EMA submissions.</li>
</ul>
<h3>Precautions</h3>
<p>Store under inert atmosphere at 2-8°C away from light. Handle with appropriate PPE to avoid inhalation or skin contact due to potential mutagenic properties associated with nitroimidazole structures.</p>
