<h3>Overview</h3>
<p>Azelastine Impurity 1 is a critical reference standard for the quality control of the antihistamine Azelastine. Synthesized via specific <strong>pharmaceutical intermediates</strong> pathways, it serves to validate purity in API manufacturing. Its molecular formula is C<sub>24</sub>H<sub>28</sub>N<sub>4</sub>O<sub>3</sub> with CAS No. 106795-76-4.</p>
<h3>Application</h3>
<ul>
<li><strong>R&D:</strong> Used as a structural elucidation tool during drug development.</li>
<li><strong>QC Testing:</strong> Applied in HPLC method validation for residual impurity identification.</li>
<li><strong>Regulatory:</strong> Essential for generating stability-indicating data in ICH guidelines.</li>
</ul>
<h3>Precautions</h3>
<p>Strictly store under inert atmosphere at 2-8°C away from light. Handling requires PPE including nitrile gloves and safety goggles to prevent dermal absorption. Not for direct clinical administration; use only in laboratory settings.</p>
