<h3>Overview</h3>
<p><strong>trans,trans-Muconic Acid-d4</strong> is a deuterium-labeled internal standard used in quantitative mass spectrometry. Synthesized via catalytic hydrogenation of benzene derivatives followed by isotopic exchange, its molecular formula is C<sub>6</sub>H<sub>2</sub>D<sub>4</sub>O<sub>4</sub>. CAS No: 15986-27-9.</p>
<h3>Application</h3>
<ul>
<li><strong>Metabolomics:</strong> Quantitative analysis of muconic acid biomarkers in biological fluids.</li>
<li><strong>Toxicology:</strong> Monitoring benzoate exposure levels in occupational health studies.</li>
<li><strong>Pharmaceutical QC:</strong> Validating assay methods for polymeric precursors.</li>
</ul>
<h3>Precautions</h3>
<p>Not for clinical administration. Store under inert atmosphere at -20°C to prevent isotopic dilution. Handle with nitrile gloves and eye protection due to potential irritant properties.</p>
