<h3>Overview</h3>
<p>Antipyrine is a classic non-opioid analgesic and antipyretic agent synthesized via the condensation of <strong>2,4-dimethylpyrazole</strong> with diethyl oxalate. Its molecular formula is <strong>C11H12N2O</strong> (CAS No. 60-80-0). This compound serves as a critical intermediate in pharmaceutical synthesis and analytical chemistry.</p>
<h3>Application</h3>
<ul>
<li><strong>Pharmaceutical Manufacturing:</strong> Used as an excipient or active ingredient in older analgesic formulations.</li>
<li><strong>Dermatological Research:</strong> Incorporated into diagnostic solutions for measuring blood flow and metabolic rates.</li>
<li><strong>Laboratory Analysis:</strong> Serves as a standard reference material in spectroscopic and chromatographic studies.</li>
</ul>
<h3>Precautions</h3>
<p>Due to potential hematological toxicity, clinical use is severely restricted in many jurisdictions. Storage requires keeping the substance in a cool, dry place away from incompatible oxidizers. Personnel must utilize appropriate PPE to prevent skin contact and inhalation of dust.</p>
