<h3>Overview</h3>
<p><strong>2-Hydroxyphenylboronic acid</strong> (CAS <strong>89466-08-0</strong>) is a versatile organoboron intermediate with molecular formula C6H7BO3. It is synthesized via lithiation of phenol followed by reaction with trialkyl borates or direct borylation methods, serving as a critical building block for Suzuki-Miyaura cross-coupling reactions in pharmaceutical and agrochemical manufacturing.</p>
<h3>Application</h3>
<ul>
<li>Synthesis of advanced API intermediates for kinase inhibitors and antiviral agents.</li>
<li>Production of functionalized liquid crystals and organic light-emitting diodes (OLEDs).</li>
<li>Preparation of specialized ligands for catalytic asymmetric synthesis.</li>
</ul>
<h3>Precautions</h3>
<p>Store under inert atmosphere at 2-8°C to prevent oxidation. Handle in a fume hood wearing appropriate PPE due to potential respiratory sensitization. Not approved for direct clinical use; strictly an industrial raw material.</p>
