Product Information

Description	Mal-PEG4-PFP ester is a PEG linker containing maleimide and PFP moieties. Maleimide is thiol-reactive and reacts between pH 6.5 and 7.5 to form thiol ester bonds. PFP moiety is amine-reactive and is less susceptible to undergoing hydrolysis. The hydrophilic PEG linker increases the water solubility of a compound in aqueous media.
Synonyms	Mal-PEG4-PFP ester; Perfluorophenyl 1-(2,5-dioxo-2H-pyrrol-1(5H)-yl)-3,6,9,12-tetraoxapentadecan-15-oate; 4,7,10,13-Tetraoxapentadecanoic acid, 15-(2,5-dihydro-2,5-dioxo-1H-pyrrol-1-yl)-, 2,3,4,5,6-pentafluorophenyl ester; 3,6,9,12-Tetraoxapentadecan-15-oic acid, 1-(2,5-dihydro-2,5-dioxo-1H-pyrrol-1-yl)-, 2,3,4,5,6-pentafluorophenyl ester; Pentafluorophenyl 1-(2,5-dioxo-2,5-dihydro-1H-pyrrol-1-yl)-3,6,9,12-tetraoxapentadecan-15-oate
