<h3>Overview</h3>
<p><strong>PEG (Carboxyl)2</strong>, or Polyethylene glycol dicarboxylic acid, is a bifunctional PEG derivative synthesized via oxidation of PEG diols. It serves as a critical linker in bioconjugation. Molecular formula: <strong>C<sub>n</sub>H<sub>2n+2</sub>O<sub>n+1</sub>(COOH)<sub>2</sub></strong>. CAS No.: <strong>varies by MW</strong>.</p>
<h3>Application</h3>
<ul>
<li>Antibody-Drug Conjugates (ADCs) for targeted cancer therapy.</li>
<li>Protein PEGylation to enhance pharmacokinetics and stability.</li>
<li>Bioactive polymer synthesis for drug delivery systems.</li>
</ul>
<h3>Precautions</h3>
<p>Store under inert atmosphere at 2-8°C. Avoid moisture to prevent hydrolysis. Handle with appropriate PPE; not for direct clinical injection without formulation.</p>
