<h3>Overview</h3>
<p><strong>Rac-Clopidogrel-d3 Hydrogen Sulfate</strong> is a deuterated internal standard for quantitative analysis of clopidogrel. It features identical physicochemical properties to the parent drug, ensuring accurate calibration in LC-MS/MS assays. Molecular Formula: C₁₆H₂₀D₃ClNO₂S·H₂SO₄; CAS: Not commercially assigned.</p>
<h3>Application</h3>
<ul>
<li><strong>Pharmaceutical R&D:</strong> Used as an isotopic standard in bioequivalence studies and pharmacokinetic profiling.</li>
<li><strong>Quality Control:</strong> Essential for validating assay methods during drug substance and formulation testing.</li>
<li><strong>Clinical Trials:</strong> Supports precise quantification of drug levels in human plasma samples.</li>
</ul>
<h3>Precautions</h3>
<p>Store under inert atmosphere at 2-8°C to prevent hydrolysis. Handle with appropriate PPE in a fume hood due to potential irritant properties. Strictly for research use only; not intended for clinical administration.</p>
