<h3>Overview</h3>
<p><strong>3-Methyl-2-oxo-butanoic acid</strong> (CAS 1985-63-3) is a key keto-acid intermediate in pharmaceutical synthesis. Its molecular formula is C<sub>5</sub>H<sub>8</sub>O<sub>3</sub>. Produced via oxidative cleavage of valine derivatives or specific catalytic oxidation, it serves as a precursor for beta-lactam antibiotics.</p>
<h3>Application</h3>
<ul>
<li>Synthesis of cephalosporin and penicillin core structures.</li>
<li>Intermediate in the production of specialized agrochemicals.</li>
<li>Research reagent for metabolic pathway studies involving branched-chain amino acids.</li>
</ul>
<h3>Precautions</h3>
<p>Store in a cool, dry, well-ventilated area away from oxidizers. Personnel must wear chemical-resistant gloves and eye protection to prevent skin irritation and respiratory exposure during handling.</p>
