<h3>Overview</h3>
<p>Ceftriaxone EP Impurity A is a critical reference standard defined in the European Pharmacopoeia for quality control of ceftriaxone sodium. Synthesized via <strong>chemical degradation</strong> pathways, it serves to validate assay methods. The compound features the molecular formula C18H17N6NaO5S2 and CAS number 90499-15-3.</p>
<h3>Application</h3>
<ul>
<li><strong>Pharmaceutical QC:</strong> Used as an analytical standard to identify and quantify trace impurities in bulk API manufacturing.</li>
<li><strong>R&D Validation:</strong> Employed in stability-indicating method development to ensure drug product purity compliance.</li>
<li><strong>Regulatory Submission:</strong> Provides data support for FDA and EMA dossiers regarding impurity profiles.</li>
</ul>
<h3>Precautions</h3>
<p>Store under <strong>controlled conditions</strong> (2-8°C) away from light to maintain stability. Handle with appropriate PPE to avoid inhalation or skin contact during weighing procedures.</p>
