<h3>Overview</h3>
<p><strong>Polyvinylpyrrolidone (PVP)</strong> is a synthetic polymer produced via radical polymerization of N-vinylpyrrolidone. With an average molecular weight of 1,300,000 (K85 grade), it features the CAS number <strong>9003-39-8</strong> and formula (C6H9NO)n.</p>
<h3>Application</h3>
<ul>
<li>Pharmaceuticals: Used as a binder in tablet formulation and solubility enhancer for poorly soluble APIs.</li>
<li>Industrial Coatings: Functions as a film former and adhesion promoter in high-viscosity paints.</li>
<li>Nanotechnology: Serves as a stabilizing agent for gold nanoparticles and metal colloids.</li>
</ul>
<h3>Precautions</h3>
<p>Store in a cool, dry place below 25°C to prevent moisture absorption and clumping. Avoid inhalation of dust; wear appropriate respiratory protection during handling. Not recommended for intravenous injection in its high-molecular-weight form due to potential renal accumulation risks.</p>
