Ald-Ph-amido-PEG2-C2-Boc(CAT: I017030) is a heterobifunctional polyethylene glycol (PEG) linker designed for advanced bioconjugation and medicinal chemistry. It features an aldehyde-functionalized aromatic (Ald-Ph) group for oxime or hydrazone ligation with aminooxy or hydrazide moieties, a PEG2-C2 spacer that enhances solubility and provides molecular flexibility, and a Boc-protected amine for orthogonal conjugation after selective deprotection. This multifunctional design allows sequential and site-specific coupling strategies while minimizing steric hindrance. Ald-Ph-amido-PEG2-C2-Boc is particularly valuable in PROTAC synthesis, drug delivery, surface functionalization, and biomaterials engineering, where stable yet adaptable linkers are required for precise molecular assembly and chemical biology applications.
