<h3>Overview</h3>
<p><strong>3-Pyridine</strong> (CAS: 109-76-2) is a fundamental heterocyclic building block synthesized via high-temperature condensation of acrolein and ammonia. Its molecular formula is C<sub>5</sub>H<sub>5</sub>N, serving as a critical precursor in pharmaceutical synthesis.</p>
<h3>Application</h3>
<ul>
<li>Agrochemicals: Intermediate for pyridine-based herbicides and fungicides.</li>
<li>Pharmaceuticals: Core scaffold for nicotinic acid derivatives and antihypertensive drugs.</li>
<li>Material Science: Solvent and ligand in coordination chemistry processes.</li>
</ul>
<h3>Precautions</h3>
<p>Store in sealed containers under inert atmosphere away from oxidizers. Requires explosion-proof ventilation due to flammability; PPE mandatory during handling to prevent respiratory irritation.</p>
