<h3>Overview</h3>
<p>Cefathiamidine Impurity 1 is a critical reference standard for the quality control of the cephalosporin antibiotic Cefathiamidine. Synthesized via <strong>peptide coupling</strong> or <strong>oxidation</strong> pathways during pharmaceutical manufacturing, it serves as an identification marker in HPLC analysis. Its molecular formula is C<sub>16</sub>H<sub>20</sub>N<sub>4</sub>O<sub>5</sub>S<sub>2</sub>, with CAS No. 89736-88-5.</p>
<h3>Application</h3>
<ul>
<li><strong>Pharmaceutical R&D:</strong> Used for method development and validation in impurity profiling.</li>
<li><strong>Quality Assurance:</strong> Essential for setting acceptance limits in bulk drug substance release testing.</li>
<li><strong>Regulatory Compliance:</strong> Supports stability-indicating studies for FDA and EMA submissions.</li>
</ul>
<h3>Precautions</h3>
<p>Store at -20°C in a dry, inert atmosphere to prevent hydrolysis. Handle with appropriate PPE due to potential allergenicity; avoid direct contact and inhalation of dust particles during weighing operations.</p>
