mPEG7-Br (CAS: 104518-25-4), also known as methyl-PEG7-bromide, is a linear PEG derivative featuring a methoxy group at one end and a reactive bromide (Br) group at the other. The bromide group serves as an excellent leaving group for nucleophilic substitution reactions, making mPEG7-Br a versatile PEG linker for introducing PEG chains into molecules or surfaces.
