<h3>Overview</h3>
<p>Ethyllithium (CAS <strong>811-49-4</strong>) is a highly reactive organolithium reagent with the molecular formula <strong>C₂H₅Li</strong>. It is primarily manufactured via the direct reaction of ethyl halides with lithium metal in hydrocarbon solvents under inert atmospheres.</p>
<h3>Application</h3>
<ul>
<li><strong>Pharmaceutical Synthesis:</strong> Used as a potent base for deprotonation and nucleophilic addition in complex molecule construction.</li>
<li><strong>Material Science:</strong> Serves as an initiator for anionic polymerization of dienes and styrenes.</li>
<li><strong>Organometallic Chemistry:</strong> Acts as a precursor for synthesizing other organolithium compounds.</li>
</ul>
<h3>Precautions</h3>
<p>This compound is pyrophoric and reacts violently with moisture. Strict storage under inert gas (nitrogen or argon) at low temperatures is mandatory. Personal protective equipment including flame-resistant gear and face shields is required during handling.</p>
