<h3>Overview</h3>
<p>Dexamethasone 21-Palmitate-d31 is a <strong>deuterium-labeled internal standard</strong> for quantitative analysis. Synthesized via esterification of Dexamethasone-21-palmitate with deuterated palmitic acid, it ensures precision in LC-MS/MS assays. Molecular formula: <strong>C38H53D31FO5</strong>; CAS: <strong>1476900-85-6</strong>.</p>
<h3>Application</h3>
<ul>
<li><strong>Pharmaceutical R&D:</strong> Quantitative determination of dexamethasone metabolites in biofluids.</li>
<li><strong>Clinical Diagnostics:</strong> Calibration for therapeutic drug monitoring and pharmacokinetic studies.</li>
<li><strong>Quality Control:</strong> Validation of stability-indicating methods in corticosteroid formulations.</li>
</ul>
<h3>Precautions</h3>
<p>Strictly for <strong>research use only</strong>, not for human administration. Store under inert atmosphere at <strong>-20°C</strong>. Handle with appropriate PPE to prevent inhalation or skin contact during weighing.</p>
