<h3>Overview</h3>
<p>P-toluenesulfonic acid is a strong organic sulfonic acid widely used as an efficient catalyst in <strong>esterification</strong> and <strong>condensation</strong> reactions. With the molecular formula <strong>C7H8O3S</strong> and CAS No. <strong>104-23-0</strong>, it serves as a standard reagent in industrial organic synthesis.</p>
<h3>Application</h3>
<ul>
<li><strong>Pharmaceuticals</strong>: Synthesis of active pharmaceutical ingredients (APIs) via catalytic dehydration.</li>
<li><strong>Polymers</strong>: Production of polyesters and resins as a polymerization initiator.</li>
<li><strong>Agrochemicals</strong>: Manufacturing intermediates for herbicides and pesticides.</li>
</ul>
<h3>Precautions</h3>
<p>Store in a cool, dry, well-ventilated area away from incompatible oxidizers. Use appropriate PPE due to severe corrosivity; skin contact causes burns. Avoid inhalation of dust or vapor.</p>
