<h3>Overview</h3>
<p><strong>2,4-Dihydroxybenzophenone-d5</strong> is a deuterated isotopologue of the UV absorber 2,4-dihydroxybenzophenone. Synthesized via selective deuteration during Friedel-Crafts acylation, it serves as an internal standard in mass spectrometry. Formula: C13H9DO5; CAS: 106287-97-6.</p>
<h3>Application</h3>
<ul>
<li>Pharmaceutical analysis for quantitative tracking of parent compound metabolism.</li>
<li>Spectroscopic calibration in HPLC and LC-MS workflows.</li>
<li>Research into photostability mechanisms of benzophenone derivatives.</li>
</ul>
<h3>Precautions</h3>
<p>Store under inert atmosphere at -20°C to prevent isotopic exchange. Use appropriate PPE to avoid inhalation or skin contact. Not intended for direct clinical administration.</p>
