<h3>Overview</h3>
<p>Ibuprofen Impurity I (EP) is a critical reference standard used in pharmaceutical quality control to monitor degradation pathways during the synthesis of ibuprofen. This impurity typically arises from side reactions or oxidation processes. Its molecular formula is <strong>C13H18O2</strong> and CAS number is <strong>57476-90-9</strong>.</p>
<h3>Application</h3>
<ul>
<li><strong>Pharmaceutical R&D:</strong> Validating synthesis routes and stability-indicating methods.</li>
<li><strong>Quality Control:</strong> Establishing acceptance limits for drug substances per EP monographs.</li>
<li><strong>Regulatory Submissions:</strong> Providing data for IND and NDA dossiers regarding impurity profiles.</li>
</ul>
<h3>Precautions</h3>
<p>Store in a cool, dry place under inert atmosphere to prevent degradation. Handle with appropriate PPE to avoid skin contact. Strictly adhere to GMP guidelines when using as a calibration standard in clinical testing environments.</p>
