<h3>Overview</h3>
<p><strong>3,5-Dichloro-4-methoxybenzoic acid</strong> (CAS: 18976-02-6; Formula: C<sub>8</sub>H<sub>6</sub>Cl<sub>2</sub>O<sub>3</sub>) is a specialized chlorinated aromatic intermediate. It is primarily synthesized via the oxidation of corresponding methyl-substituted precursors or direct electrophilic chlorination followed by methylation.</p>
<h3>Application</h3>
<ul>
<li><strong>Pharmaceuticals:</strong> Key building block for synthesizing non-steroidal anti-inflammatory drugs (NSAIDs) and heterocyclic APIs.</li>
<li><strong>Agrichemicals:</strong> Used as an intermediate in producing herbicides and fungicides targeting specific crop pathogens.</li>
<li><strong>Materials Science:</strong> Utilized in the development of high-performance liquid crystal polymers and functional dyes.</li>
</ul>
<h3>Precautions</h3>
<p>Store in a cool, dry, well-ventilated area away from oxidizers. Use appropriate PPE including gloves and eye protection to prevent skin irritation. Avoid inhalation of dust particles during handling.</p>
