<h3>Overview</h3>
<p><strong>Neostigmine EP Impurity C</strong>, also known as <strong>Nor Neostigmine</strong>, is a critical reference standard used for quality control in pharmaceutical manufacturing. It arises from the demethylation process during the synthesis of neostigmine bromide. The molecular formula is <strong>C12H19N2O2+</strong> with CAS No. <strong>50-84-0</strong>.</p>
<h3>Application</h3>
<ul>
<li><strong>Pharmaceutical QC:</strong> Used as an analytical standard to detect and quantify impurities in active pharmaceutical ingredients (APIs).</li>
<li><strong>R&D:</strong> Employed in method development and validation for high-performance liquid chromatography (HPLC) assays.</li>
<li><strong>Regulatory Compliance:</strong> Supports stability studies to ensure drug safety according to ICH guidelines.</li>
</ul>
<h3>Precautions</h3>
<p>Store under inert atmosphere at 2-8°C protected from light. Handle with appropriate PPE to avoid skin contact or inhalation due to potential cholinergic toxicity. Strictly limit use to laboratory analysis; not for clinical administration.</p>
