<h3>Overview</h3>
<p><strong>Bupivacaine N-Oxide Hydrochloride Salt</strong> is a synthetic metabolite and impurity of the local anesthetic bupivacaine, typically generated via oxidative pathways during manufacturing or storage. The molecular formula is C<sub>18</sub>H<sub>29</sub>N<sub>2</sub>O<sub>2</sub>Cl, with CAS number 10534-63-7.</p>
<h3>Application</h3>
<ul>
<li><strong>Pharmaceutical Quality Control:</strong> Serves as a reference standard for identifying and quantifying degradation products in drug stability studies.</li>
<li><strong>Toxicological Research:</strong> Utilized to evaluate the metabolic fate and potential toxicity profiles of bupivacaine formulations.</li>
<li><strong>Impurity Profiling:</strong> Essential for validating purification processes in API synthesis to ensure compliance with ICH guidelines.</li>
</ul>
<h3>Precautions</h3>
<p>Strictly limit exposure to prevent inhalation or skin contact; store in sealed containers at controlled temperatures (2-8°C) away from oxidizing agents. Not intended for direct clinical administration due to lack of therapeutic efficacy and potential adverse effects.</p>
