<h3>Overview</h3>
<p>Cyclen (1,4,7,10-Tetraazacyclododecane) is a <strong>cyclic tetramine</strong> macrocycle synthesized via high-dilution condensation. Its <strong>chemical formula</strong> is C<sub>8</sub>H<sub>20</sub>N<sub>4</sub> and <strong>CAS No.</strong> 2964-52-7, serving as a critical chelating scaffold for radiometal coordination.</p>
<h3>Application</h3>
<ul>
<li><strong>Radio-pharmaceuticals:</strong> Chelation of radionuclides like <sup>68</sup>Ga or <sup>177</sup>Lu for PET imaging and targeted therapy.</li>
<li><strong>MRI Contrast Agents:</strong> Development of gadolinium-based complexes to enhance diagnostic resolution.</li>
<li><strong>Luminescent Sensors:</strong> Construction of europium/tb complexes for biological sensing applications.</li>
</ul>
<h3>Precautions</h3>
<p>Strictly store under inert atmosphere at <strong>2-8°C</strong> to prevent oxidation. Avoid inhalation; use appropriate PPE including respirators and gloves. Not approved for direct clinical administration without metal complexation.</p>
