<h3>Overview</h3>
<p><strong>Methoxy PEG Alkyne</strong> is a functionalized polyethylene glycol derivative featuring a terminal alkyne group and a methoxy cap. It serves as a critical reagent for bioconjugation via copper-catalyzed azide-alkyne cycloaddition (CuAAC). The standard molecular formula is C<sub>n</sub>H<sub>2n+2</sub>O<sub>n+1</sub>(CH<sub>2</sub>)<sub>m</sub>C≡CH, with CAS No. varying by PEG chain length (e.g., 78659-06-4 for MW 2k).</p>
<h3>Application</h3>
<ul>
<li><strong>Drug Discovery:</strong> Synthesis of antibody-drug conjugates (ADCs) and peptide libraries.</li>
<li><strong>Diagnostics:</strong> Labeling biomolecules for flow cytometry and imaging probes.</li>
<li><strong>Material Science:</strong> Grafting polymers onto surfaces for hydrogel fabrication.</li>
</ul>
<h3>Precautions</h3>
<p>Store under inert atmosphere at -20°C to prevent oxidation. Handle in fume hoods due to potential irritancy. Not approved for direct clinical administration without purification; strictly for research use only.</p>
