<h3>Overview</h3>
<p><strong>4-Carboxyphenylboronic acid</strong> (CAS: 6185-79-1, Formula: C7H7BO4) is a specialized organoboron intermediate synthesized via directed borylation of benzoic acid derivatives. It serves as a critical precursor in cross-coupling reactions for pharmaceutical manufacturing.</p>
<h3>Application</h3>
<ul>
<li><strong>Pharmaceuticals:</strong> Synthesis of kinase inhibitors and antiviral agents.</li>
<li><strong>Agrochemicals:</strong> Production of novel herbicides with boron-based activity.</li>
<li><strong>Materials Science:</strong> Fabrication of boron-doped polymers for advanced sensors.</li>
</ul>
<h3>Precautions</h3>
<p>Store in sealed containers under inert atmosphere at 2-8°C to prevent hydrolysis. Use appropriate PPE including gloves and goggles due to potential skin irritation and respiratory hazards during handling.</p>
