<h3>Overview</h3>
<p><strong>Pyridoxine Cyclic Ether Impurity Hydrochloride Salt</strong> is a critical reference standard used in pharmaceutical quality control. It serves as an identified impurity derived from the synthesis or degradation of Vitamin B6 (Pyridoxine). The molecular formula is typically C8H12ClNO2, with CAS No. 1074-95-5.</p>
<h3>Application</h3>
<ul>
<li><strong>Quality Control:</strong> Used to validate HPLC and GC methods for detecting trace levels in active pharmaceutical ingredients.</li>
<li><strong>R&D:</strong> Applied in stability studies to monitor degradation pathways during formulation development.</li>
<li><strong>Regulatory Compliance:</strong> Essential for generating toxicological data required by ICH guidelines for drug registration.</li>
</ul>
<h3>Precautions</h3>
<ul>
<li><strong>Storage:</strong> Keep in a cool, dry place under inert atmosphere; protect from light and moisture.</li>
<li><strong>Safety:</strong> Wear appropriate PPE; avoid inhalation or skin contact due to potential irritancy.</li>
<li><strong>Usage:</strong> Strictly for analytical research only; not intended for human therapeutic use.</li>
