<h3>Overview</h3>
<p><strong>4-Methylamino Antipyrine</strong> is a synthetic pyrazolone derivative produced via N-methylation of aminoantipyrine. It serves as a key intermediate in pharmaceutical synthesis, particularly for analgesic and antipyretic compounds. The molecular formula is <strong>C12H16N4O</strong>, with CAS No. <strong>90-78-4</strong>.</p>
<h3>Application</h3>
<ul>
<li>Pharmaceutical manufacturing: Precursor for pain relief formulations.</li>
<li>Diagnostics: Used in specific colorimetric assay reagents.</li>
<li>Research: Standard reference material for metabolic studies.</li>
</ul>
<h3>Precautions</h3>
<p>Strictly avoid use in patients with known hypersensitivity to pyrazolones. Store in cool, dry conditions away from light. Personal protective equipment (PPE) including gloves and goggles is mandatory during handling to prevent skin irritation and inhalation risks.</p>
