<h3>Overview</h3>
<p><strong>(R,S)-N-Nitroso Anabasine-d4</strong> is a deuterated internal standard for mass spectrometry, synthesized via isotopic exchange or specific deuteration of the parent nitrosamine. Its molecular formula is C10H12D5N3O and CAS number is typically unlisted commercially due to custom synthesis.</p>
<h3>Application</h3>
<ul>
<li><strong>Pharmaceutical Analysis:</strong> Quantification of anabasine metabolites in ADME studies.</li>
<li><strong>Toxicology:</strong> Monitoring N-nitroso compounds in environmental water samples.</li>
<li><strong>Quality Control:</strong> Calibration reference for LC-MS/MS instrumentation.</li>
</ul>
<h3>Precautions</h3>
<p>Store at -20°C under inert atmosphere; handle as a potential carcinogen with strict PPE compliance per OSHA guidelines.</p>
