<h3>Overview</h3>
<p>Amlodipine Impurity A (EP) is a critical reference standard for the quality control of the calcium channel blocker Amlodipine. Synthesized via specific <strong>chemical degradation</strong> pathways, it ensures compliance with European Pharmacopoeia limits. Its molecular formula is C<sub>20</sub>H<sub>25</sub>ClN<sub>2</sub>O<sub>5</sub> and CAS number is 148679-88-1.</p>
<h3>Application</h3>
<ul>
<li><strong>Pharmaceutical Manufacturing:</strong> Used as an internal standard in HPLC method validation to detect trace impurities in active pharmaceutical ingredients.</li>
<li><strong>Regulatory Compliance:</strong> Essential for stability testing dossiers submitted to EMA and other global health authorities.</li>
<li><strong>R&D Analysis:</strong> Supports structural elucidation during process development and impurity profiling studies.</li>
</ul>
<h3>Precautions</h3>
<p>Store under <strong>controlled temperature</strong> conditions (typically 2-8°C) in a dry environment away from light. Handle only with appropriate PPE; avoid inhalation or skin contact as it is not intended for direct clinical use.</p>
