<h3>Overview</h3>
<p>Methadone Impurity D is a critical reference standard used in pharmaceutical quality control for <strong>opioid analgesics</strong>. Synthesized via controlled chemical pathways, it serves to identify and quantify degradation products. Its molecular formula is <strong>C21H27NO2</strong> and CAS number is <strong>1504-86-9</strong>.</p>
<h3>Application</h3>
<ul>
<li><strong>Quality Assurance:</strong> Validating purity profiles during Methadone hydrochloride manufacturing.</li>
<li><strong>R&D:</strong> Supporting stability studies and method development in analytical labs.</li>
<li><strong>Regulatory Compliance:</strong> Meeting ICH guidelines for impurity identification in drug dossiers.</li>
</ul>
<h3>Precautions</h3>
<p>Strictly handle under controlled ventilation with PPE due to narcotic potential. Store in sealed containers at <strong>-20°C</strong> away from light to prevent degradation. Use only by certified laboratories.</p>
