<h3>Overview</h3>
<p><strong>Entecavir Intermediate (ETA)</strong> is a key chiral building block synthesized via asymmetric hydrogenation or enzymatic resolution for antiviral drug production. It serves as the critical precursor in the multi-step synthesis of Entecavir, an FDA-approved nucleoside analog.</p>
<h3>Application</h3>
<ul>
<li><li>Pharmaceutical Manufacturing: Synthesis of Entecavir for chronic Hepatitis B virus (HBV) treatment.</li></li>
<li><li>R&D Laboratories: Reference standards and process development for novel antiviral compounds.</li></li>
<li><li>Clinical Trials: Supplying active pharmaceutical ingredients (APIs) for efficacy studies.</li></li>
</ul>
<h3>Precautions</h3>
<p>Store in sealed containers at 2-8°C away from light. Avoid inhalation and skin contact; use appropriate PPE. Not for direct human consumption; strictly regulated under GMP guidelines for API intermediates.</p>
