Ald-PEG-NHS ester

Ald-PEG-NHS ester is a type of functional group that is commonly used in pharmaceutical research and development. This group consists of a polyethylene glycol (PEG) chain that has been modified with an N-hydroxysuccinimide (NHS) ester group, which allows it to react with primary amines and form stable amide bonds. This reactivity makes Ald-PEG-NHS ester an attractive tool for conjugation reactions in drug delivery systems, as it can be used to attach drugs or other molecules to specific target sites in the body. Additionally, the PEG chain can increase the solubility and circulation time of the conjugated molecule, improving its pharmacokinetic properties.
