<h3>Overview</h3>
<p><strong>Octinoxate-d3</strong> is the deuterated internal standard for Octinoxate (Ethylhexyl Methoxycinnamate), utilized in LC-MS/MS quantification. Synthesized via isotopic substitution during esterification, its molecular formula is C18H25D3O3 and CAS No. is 109476-48-8.</p>
<h3>Application</h3>
<ul>
<li><li>Pharmaceutical Analysis: Serves as a tracer in bioequivalence studies for UV filters.</li>
<li><li>Cosmetic Quality Control: Validates stability and concentration in sunscreens.</li>
<li><li>Environmental Monitoring: Tracks photodegradation products in water systems.</li></li></ul>
<h3>Precautions</h3>
<p>Store under inert atmosphere at -20°C to prevent isotopic exchange. Handle with PPE to avoid skin contact; strictly for laboratory research use only, not for clinical or consumer applications.</p>
