N-Mal-N-bis(PEG4-acid) Chemical Properties, Uses, Production

Description

N-Mal-N-bis(PEG4-acid) is an Maleimide PEG reagent with two terminal carboxylic acids and a maleimide (Mal) group. Maleimide (Mal) reacts specifically with sulfhydryl groups to form a stable thioether linkage when the pH is between 6.5 and 7.5. The terminal carboxylic acids can conjugate with iamine-containing molecule in the presence of activators (e.g. EDC, or HATU) to form a stable amide bond.

Uses

Mal-N-bis(PEG4-C2-acid) is a PEG-based PROTAC linker that can be used in the synthesis of PROTACs[1].
