<h3>Overview</h3>
<p><strong>2-Methyl-3-isothiazolone-d3 Hydrochloride</strong> is a deuterated isotopic standard derived from the biocide 2-methylisothiazolinone. Synthesized via selective deuteration of the methyl group followed by hydrochloride salt formation, it serves as an internal reference in quantitative analysis. Molecular Formula: C5H6ClNOS-D3; CAS No.: Not publicly indexed for commercial bulk trade.</p>
<h3>Application</h3>
<ul>
<li>Pharmaceutical research: Metabolite tracing and ADME studies.</li>
<li>Quality control: Calibration of LC-MS/MS instruments.</li>
<li>Environmental monitoring: Quantifying residual isothiazolones in water samples.</li>
</ul>
<h3>Precautions</h3>
<p>Store under inert atmosphere at -20°C to prevent degradation. Avoid direct skin contact; use appropriate PPE including nitrile gloves and safety goggles. Not intended for human or veterinary therapeutic use.</p>
