<h3>Overview</h3>
<p>BnO-PEG8-OH is a benzyl-protected polyethylene glycol derivative featuring an eight-unit oligoether chain. This intermediate is synthesized via etherification of PEG with benzyl chloride, followed by deprotection or specific functionalization. The molecular formula is <strong>C24H40O9</strong> (CAS: 167569-47-9).</p>
<h3>Application</h3>
<ul>
<li><strong>Pharmaceutical Conjugation:</strong> Serves as a linker for antibody-drug conjugates (ADCs) requiring cleavable protecting groups.</li>
<li><strong>Peptide Synthesis:</strong> Utilized in solid-phase synthesis to introduce hydrophilic spacers while preventing side reactions.</li>
<li><strong>Material Science:</strong> Functionalizes surfaces to create biocompatible coatings for medical devices.</li>
</ul>
<h3>Precautions</h3>
<ul>
<li><strong>Safety:</strong> Handle under inert atmosphere; avoid contact with strong oxidizers and moisture.</li>
<li><strong>Storage:</strong> Store sealed at -20°C in dry conditions to prevent hydrolysis of the benzyl ether linkage.</li>
<li><strong>Regulatory:</strong> Not approved for direct clinical use; intended strictly for research and manufacturing intermediates.</li>
</ul>
