<h3>Overview</h3>
<p>Nonafluorobutanesulfonyl fluoride (CAS: <strong>13948-25-7</strong>) is a highly fluorinated sulfonylating agent. Synthesized via electrophilic fluorination of butanesulfonyl precursors, it features the molecular formula <strong>C4F9SO2F</strong>. This reagent is critical for introducing perfluorobutylsulfonyl groups into organic frameworks.</p>
<h3>Application</h3>
<ul>
<li><strong>Pharmaceuticals:</strong> Synthesis of fluorinated APIs and radiotracers.</li>
<li><strong>Agricultural Chemistry:</strong> Production of novel herbicides and fungicides.</li>
<li><strong>Materials Science:</strong> Fabrication of high-performance fluoropolymers.</li>
</ul>
<h3>Precautions</h3>
<p>Strictly store in sealed, dry containers under inert atmosphere at controlled temperatures. Use full PPE including acid-resistant gloves due to severe corrosivity and hydrolysis risks releasing HF gas. Avoid inhalation or skin contact.</p>
