<h3>Overview</h3>
<p><strong>Paracetamol EP Impurity E</strong> (4-Aminophenol) is a critical degradation product and synthetic intermediate in pharmaceutical manufacturing. It serves as the primary starting material for <strong>paracetamol</strong> synthesis via acetylation. CAS No: 123-30-8; Formula: C6H7NO.</p>
<h3>Application</h3>
<ul>
<li><strong>Quality Control:</strong> Used as reference standard for HPLC identification of impurities in paracetamol APIs per EP monographs.</li>
<li><strong>Synthesis:</strong> Acts as the essential precursor for large-scale production of acetaminophen analgesics.</li>
<li><strong>R&D:</strong> Employed in stability testing to monitor oxidative degradation pathways of finished dosage forms.</li>
</ul>
<h3>Precautions</h3>
<p>Strictly limit exposure due to potential carcinogenicity; handle in ventilated fume hoods with appropriate PPE. Store under inert atmosphere at cool, dry conditions below 25°C to prevent oxidation. Avoid ingestion or inhalation of dust particles.</p>
