<h3>Overview</h3>
<p>Cefoxitin EP Impurity E, also known as <strong>R-methoxy cefoxitin</strong>, is a critical chiral reference standard used in pharmaceutical quality control. It represents the R-enantiomer impurity arising during the synthesis of the cephamycin antibiotic Cefoxitin. The molecular formula is C<sub>16</sub>H<sub>17</sub>N<sub>3</sub>O<sub>8</sub>S (CAS: 59042-58-7). This compound is essential for validating stereoselectivity in manufacturing processes.</p>
<h3>Application</h3>
<ul>
<li><strong>Quality Control:</strong> Serves as a primary standard for HPLC method validation to detect and quantify enantiomeric impurities.</li>
<li><strong>R&D:</strong> Utilized in stability studies to monitor degradation pathways of Cefoxitin formulations.</li>
<li><strong>Regulatory Compliance:</strong> Required for filing dossiers with agencies like EMA and FDA to ensure stereochemical purity.</li>
</ul>
<h3>Precautions</h3>
<p>Store under inert atmosphere at -20°C to prevent hydrolysis and racemization. Handle only in certified laboratories using appropriate PPE due to potential sensitization risks. Not intended for direct clinical use; strictly for analytical purposes.</p>
