<h3>Overview</h3>
<p>Diazepam Impurity D (EP) is a critical reference standard for pharmaceutical quality control, specifically defined in the European Pharmacopoeia. It serves as an analytical benchmark to identify and quantify degradation products during Diazepam manufacturing. The compound features <strong>molecular formula C16H13ClN2O</strong> and <strong>CAS number 2847-90-5</strong>, representing a specific oxidative impurity.</p>
<h3>Application</h3>
<ul>
<li><strong>Quality Control:</strong> Used in HPLC method validation to ensure purity of bulk active pharmaceutical ingredients.</li>
<li><strong>Stability Testing:</strong> Monitors drug product shelf-life by detecting oxidative degradation pathways.</li>
<li><strong>R&D:</strong> Supports process optimization in synthesis routes to minimize impurity formation.</li>
</ul>
<h3>Precautions</h3>
<p>Store strictly under <strong>inert atmosphere</strong> at controlled temperatures below -20°C to prevent oxidation. Handle with appropriate PPE including nitrile gloves and safety goggles due to potential sensitization risks. Avoid inhalation of dust particles during weighing procedures.</p>
