DNP-PEG4-NHS ester

DNP-PEG4-NHS ester is a PEG linker containing a DNP moiety and NHS ester terminal group. DNP is involved in biological applications such as participating in ion transport across membranes. The NHS ester can react with primary amines to form stable amide bonds. The hydrophilic PEG linkers increase the water solubility of the compound in aqueous media.

DNP-PEG4-NHS ester is a PEG-based PROTAC linker that can be used in the synthesis of PROTACs[1].
