<h3>Overview</h3>
<p>Melengestrol Acetate-d3 is a deuterium-labeled internal standard for quantitative analysis of the synthetic progestin Melengestrol Acetate. Synthesized via isotopic substitution, it maintains identical physicochemical properties to the native compound. Molecular formula: C24H31DO4; CAS No.: 100968-75-4.</p>
<h3>Application</h3>
<ul>
<li><strong>Pharmaceutical R&D:</strong> Used as an analytical reference in bioequivalence studies and pharmacokinetic profiling.</li>
<li><strong>Clinical Toxicology:</strong> Serves as a tracer for mass spectrometry-based quantification in biological matrices.</li>
<li><strong>Veterinary Research:</strong> Applied in residue analysis for animal feed additives containing MGA.</li>
</ul>
<h3>Precautions</h3>
<p>Store at -20°C under inert atmosphere to prevent isotopic exchange or degradation. Handle with appropriate PPE; avoid inhalation or skin contact. Strictly regulated for research use only, not for clinical administration.</p>
