<h3>Overview</h3>
<p><strong>Levofloxacin Impurity D</strong> is a critical reference standard defined as 1,4-dihydro-7-methyl-9-fluoro-5-oxo-1-(2,2,2-trifluoroethyl)-4H-pyrido[3,2,1-ij]quinoline-3-carboxylic acid. Its molecular formula is C18H16F3N3O3 with CAS No. 140566-05-0. This compound serves as an essential process impurity generated during the synthesis of levofloxacin via asymmetric catalysis.</p>
<h3>Application</h3>
<ul>
<li>Quality control testing in pharmaceutical manufacturing for assay validation.</li>
<li>Method development and validation for HPLC/GC analytical procedures.</li>
<li>Regulatory compliance documentation for ICH Q3A/B impurity profiling.</li>
</ul>
<h3>Precautions</h3>
<p>Store under inert atmosphere at -20°C to prevent degradation. Handle with appropriate PPE due to potential mutagenicity. Strictly limit clinical use to laboratory research only; not for human therapeutic application.</p>
