Fmoc-PEG-NHS ester is a functional group commonly used in drug research and development. It belongs to the family of N-hydroxysuccinimide (NHS) esters, which are widely used for the covalent modification of biomolecules such as proteins, peptides, and nucleic acids. Fmoc-PEG-NHS ester is a derivative of polyethylene glycol (PEG) that is modified with an N-(9-fluorenylmethoxycarbonyl) (Fmoc) group and an NHS ester group. The Fmoc group serves as a temporary protecting group that can be removed under mild conditions, while the NHS ester group is reactive towards primary amines, enabling the conjugation of PEG to a variety of molecules.

In drug research and development, Fmoc-PEG-NHS ester is used to modify peptides and proteins to improve their pharmacokinetic properties, such as solubility, stability, and circulation time. It can also be used to attach targeting moieties or imaging agents to drug molecules for improved specificity and efficacy.
