4-Arm PEG-NH2 (MW 5000)
PEG Derivative
4-Arm PEG-NH2 (MW 5000) is a multi-arm polyethylene glycol (PEG) derivative featuring primary amine groups at the termini of four arms connected to a pentaerythritol core. The reactive NH2 groups readily engage in conjugation with activated carboxylic acids, such as NHS esters, facilitating the formation of stable amide bonds. This reagent is suitable for applications in bioconjugation, drug delivery, and the development of biomaterials, enabling precise modifications and enhanced solubility in biological systems.
