<h3>Overview</h3>
<p><strong>7-Amino-4-(trifluoromethyl)coumarin</strong> (CAS 105983-26-2, Formula C<sub>11</sub>H<sub>6</sub>F<sub>3</sub>NO<sub>2</sub>) is a fluorinated coumarin derivative synthesized via condensation of trifluoroacetophenone and amino acid precursors. It serves as a critical fluorogenic substrate for protease activity assays.</p>
<h3>Application</h3>
<ul>
<li>Development of fluorescent probes for caspase and cathepsin detection in oncology research.</li>
<li>Quality control of thrombin inhibitors during pharmaceutical manufacturing.</li>
<li>Fluorescence resonance energy transfer (FRET) system components in high-throughput screening.</li>
</ul>
<h3>Precautions</h3>
<p>Store under inert atmosphere at -20°C to prevent photodegradation. Use appropriate PPE including nitrile gloves and fume hoods due to potential sensitization risks associated with trifluoromethyl groups.</p>
