Mal-PEG5-acid is a PEG-based PROTAC linker used in the synthesis of PROTACs. PROTACs consist of two distinct ligands connected by a linker, where one ligand targets an E3 ubiquitin ligase and the other targets a specific protein. These molecules function by harnessing the intracellular ubiquitin-proteasome system to selectively degrade target proteins. Its molecular weight is 389.40, with a chemical formula of C17H27NO9. It appears as a liquid, light brown to yellow in color, with a density of 1.249±0.06 g/cm3.
