<h3>Overview</h3>
<p><strong>4-tert-Butylphenylboronic acid</strong> (CAS 2501-98-6, C10H15BO2) is a specialized organoboron intermediate synthesized via lithiation of tert-butylbenzene followed by boric acid treatment. It serves as a critical coupling agent in Pd-catalyzed cross-coupling reactions.</p>
<h3>Application</h3>
<ul>
<li><strong>Pharmaceuticals:</strong> Synthesis of complex APIs and biologically active heterocycles.</li>
<li><strong>Agrichemicals:</strong> Production of herbicides and fungicides requiring precise boron motifs.</li>
<li><strong>Materials Science:</strong> Fabrication of functionalized liquid crystals and organic semiconductors.</li>
</ul>
<h3>Precautions</h3>
<p>Store in sealed containers under inert atmosphere at 2-8°C to prevent oxidation. Use appropriate PPE; avoid inhalation or skin contact due to potential irritancy.</p>
