<h3>Overview</h3>
<p>Cefepime-D8 Sulfate is a deuterated internal standard for <strong>LC-MS/MS</strong> analysis. Synthesized via isotopic substitution, it matches the physicochemical properties of cefepime sulfate (<strong>C23H26N6O7S2</strong>, CAS <strong>109458-44-6</strong>). This stable isotope ensures high precision in quantitative assays.</p>
<h3>Application</h3>
<ul>
<li><strong>Pharmaceutical QC:</strong> Validating purity and content uniformity in bulk drug substances.</li>
<li><strong>Metabolism Studies:</strong> Tracking metabolic pathways and bioavailability in clinical trials.</li>
<li><strong>Environmental Analysis:</strong> Detecting trace antibiotic residues in wastewater systems.</li>
</ul>
<h3>Precautions</h3>
<p>Store at <strong>-20°C</strong> under inert atmosphere to prevent hydrolysis. Handle with appropriate PPE; avoid direct contact as it is not for human administration. Maintain strict chain-of-custody records.</p>
