<h3>Overview</h3>
<p>Methyl Paraben-13C6 is a <strong>stable isotope-labeled internal standard</strong> used primarily in mass spectrometry for quantitative analysis. Synthesized via isotopic exchange or specific synthesis routes, it matches the structure of methylparaben with six deuterium atoms replacing hydrogen on the methyl group. The molecular formula is C<sub>8</sub>H<sub>7</sub>D<sub>6</sub>O<sub>3</sub>, and its CAS number remains associated with the parent compound.</p>
<h3>Application</h3>
<ul>
<li><strong>Pharmaceutical Analysis:</strong> Quantification of preservatives in drug formulations during stability testing.</li>
<li><strong>Metabolomics:</strong> Tracing metabolic pathways of parabens in biological matrices.</li>
<li><strong>Cosmetic Quality Control:</strong> Accurate measurement of preservative levels in consumer products.</li>
</ul>
<h3>Precautions</h3>
<p>Store under inert atmosphere at -20°C to prevent degradation. Handle in certified fume hoods using appropriate PPE due to potential toxicity upon inhalation or skin contact. Strictly adhere to regulatory limits regarding residue in clinical samples.</p>
