<h3>Overview</h3>
<p><strong>7-Ethyl-Camptothecin</strong> (Topotecan precursor) is a semi-synthetic analog of camptothecin used in oncology research. Its molecular formula is C21H20N2O4 with CAS <strong>96182-56-8</strong>. Industrial synthesis typically involves the modification of natural camptothecin derivatives via ethylation processes under controlled conditions.</p>
<h3>Application</h3>
<ul>
<li>Oncology drug development for topoisomerase I inhibitors</li>
<li>Preclinical research into anti-cancer mechanisms</li>
<li>Synthesis of advanced pharmaceutical intermediates</li>
</ul>
<h3>Precautions</h3>
<p>Strictly store at -20°C in a dry, dark environment. Handle only in certified laboratories due to cytotoxicity; avoid direct skin contact and inhalation. Not approved for clinical use as a standalone therapeutic agent.</p>
