<h3>Overview</h3>
<p>Indocyanine Green (ICG) is a near-infrared fluorescent dye used primarily for <strong>medical imaging</strong>. Synthesized via condensation of 1,8-dihydroxynaphthalene-3,6-disulfonic acid with thiourea, its chemical structure corresponds to CAS <strong>309-47-3</strong> and molecular formula C<sub>43</sub>H<sub>47</sub>N<sub>2</sub>Na<sub>2</sub>O<sub>6</sub>S<sub>3</sub>.</p>
<h3>Application</h3>
<ul>
<li><strong>Ophthalmology:</strong> Angiography for retinal and choroidal blood flow assessment.</li>
<li><strong>Hepatology:</strong> Evaluation of liver function and indocyanine green clearance tests.</li>
<li><strong>Surgical Guidance:</strong> Real-time visualization of lymphatic vessels and tissue perfusion during oncologic procedures.</li>
<li><strong>Cardiovascular:</strong> Cardiac output measurement using pulse densitometry.</li>
</ul>
<h3>Precautions</h3>
<p>Contraindicated in patients with known hypersensitivity to iodine or ICG. Store lyophilized powder in a cool, dry place protected from light. Reconstituted solutions must be used immediately as they degrade rapidly under ambient conditions.</p>
