<h3>Overview</h3>
<p>Cesium hydroxide (<strong>CsOH</strong>, CAS <strong>1306-96-9</strong>) is a strong inorganic base produced via the reaction of cesium metal or carbonate with water. It serves as a critical catalyst and pH regulator in industrial synthesis.</p>
<h3>Application</h3>
<ul>
<li><strong>Pharmaceuticals:</strong> Catalyzing nucleophilic substitutions in drug manufacturing.</li>
<li><strong>Semiconductors:</strong> Used for high-purity etching processes.</li>
<li><strong>Laboratory Reagents:</strong> Standardized titration and organic synthesis.</li>
</ul>
<h3>Precautions</h3>
<p>Strictly store in airtight containers to prevent moisture absorption. Requires PPE against severe corrosive burns; incompatible with acids and reactive metals.</p>
