propargyl-peg-5-amine

Propargyl-PEG5-amine is a non-cleavable linker compound used extensively in the synthesis of antibody–drug conjugates (ADCs) and PROTACs, and Propargyl-PEG5-amine functions as a PEG-based connector that facilitates stable conjugation between molecular components. Propargyl-PEG5-amine supports modular assembly strategies in targeted therapeutic design by providing a robust, hydrophilic spacer that enhances solubility and structural flexibility during ADC and PROTAC construction, which enables the efficient bio-conjugation workflows in chemical biology and medicinal chemistry research.
