Medchemexpress LLC Acetamide, 2-(aminooxy)-N-3,6,9,12-tetraoxapentadec-14-yn-1-yl- | 2253965-03-4 | 97.0% | 304.34 g/mol | C13H24N2O6 | 50 MG

Aminooxy-amido-PEG4-propargyl is a PEG4-based linker reagent used for bioconjugation and linker installation in research applications. It contains an aminooxy group and a terminal alkyne that enable orthogonal conjugation chemistry, and the PEG4 spacer improves solubility and flexibility for bioconjugates.

Contains aminooxy group for oxime ligation or conjugation.
Contains terminal alkyne (propargyl) for copper-catalyzed azide-alkyne cycloaddition.
PEG4 spacer increases solubility and reduces steric hindrance in conjugates.
High reported purity (97.0%) suitable for research applications.
Viscous, colorless to light yellow physical form for handling.
Available in small research pack size for lab-scale use.
