<h3>Overview</h3>
<p>(S)-ethyl 2-amino-3-(4-(2-amino-6-((R)-1-(4-chloro-2-(3-methyl-1H-pyrazol-1-yl)phenyl)-2,2,2-trifluoroethyl)pyrazolo[1,5-a]pyrimidin-7-yl)phenoxy)propanoate is a chiral intermediate for antiviral drugs. Synthesized via asymmetric catalysis, its <strong>molecular formula</strong> and <strong>CAS number</strong> remain proprietary pending verification.</p>
<h3>Application</h3>
<ul>
<li><strong>Pharmaceutical Manufacturing</strong>: Critical building block for developing novel SARS-CoV-2 inhibitors.</li>
<li><strong>Medicinal Chemistry</strong>: Used in library synthesis to optimize binding affinity against viral proteases.</li>
</ul>
<h3>Precautions</h3>
<p>Store under inert atmosphere at -20°C to prevent racemization. Strictly limit exposure during clinical trials due to unknown toxicity profiles; handle with full PPE in fume hoods.</p>
