<h3>Overview</h3>
<p><strong>Triphenylphosphine</strong> (CAS: 603-35-0) is a ubiquitous organophosphorus reagent with molecular formula <strong>P(C₆H₅)₃</strong>. It serves as a critical ligand in catalysis and a reducing agent in organic synthesis, primarily produced via the reaction of phosphorus trichloride with benzene.</p>
<h3>Application</h3>
<ul>
<li><strong>Pharmaceuticals:</strong> Key component in Mitsunobu reactions for esterification and amide coupling.</li>
<li><strong>Petrochemicals:</strong> Essential catalyst precursor in olefin metathesis and hydrogenation processes.</li>
<li><strong>Materials Science:</strong> Used in synthesizing phosphonium salts for polymer stabilization and OLED fabrication.</li>
</ul>
<h3>Precautions</h3>
<p>Store under inert atmosphere to prevent oxidation. Avoid inhalation of dust; use appropriate PPE including respirators and chemical-resistant gloves due to potential toxicity and skin irritation.</p>
