<h3>Overview</h3>
<p><strong>2-Furaldehyde</strong> (CAS 98-01-1), also known as furfural, is a heterocyclic aldehyde produced via acid-catalyzed hydrolysis of pentosans in agricultural residues. Its molecular formula is C<sub>5</sub>H<sub>4</sub>O<sub>2</sub>. It serves as a critical platform chemical for sustainable solvent and polymer synthesis.</p>
<h3>Application</h3>
<ul>
<li>Production of tetrahydrofuran (THF) and gamma-butyrolactone (GBL).</li>
<li>Synthesis of furan resins for foundry sand binders.</li>
<li>Extraction agent in petroleum refining and lubricant processing.</li>
<li>Raw material for pharmaceutical intermediates and agrochemicals.</li>
</ul>
<h3>Precautions</h3>
<p>Store in cool, ventilated areas away from oxidizers. Requires PPE due to skin irritation risks and flammability. Not intended for direct human consumption; strict industrial handling protocols apply.</p>
