<h3>Overview</h3>
<p><strong>4-(Chloromethyl)benzoyl chloride</strong> (CAS 1009-76-5; C<sub>8</sub>H<sub>6</sub>Cl<sub>2</sub>O) is a key chlorinating agent synthesized via side-chain chlorination of p-tolyl derivatives. It serves as a critical intermediate in organic synthesis.</p>
<h3>Application</h3>
<ul>
<li><li>Pharmaceuticals: Synthesis of benzodiazepines and antihistamines.</li></li>
<li><li>Polymer Industry: Production of high-performance liquid crystal polymers.</li></li>
<li><li>Agricultural Chemicals: Precursor for specific herbicides and fungicides.</li></li>
</ul>
<h3>Precautions</h3>
<p>Strictly store under inert atmosphere at controlled temperatures below 25°C. Requires PPE due to severe corrosivity and moisture sensitivity; hydrolysis releases toxic HCl fumes.</p>
