m-PEG6-Br(CAT: I016461) is a polyethylene glycol derivative containing a six-unit PEG spacer terminated with a bromide functional group. The PEG6 chain provides hydrophilicity, flexibility, and improved solubility, while the reactive bromide moiety serves as a versatile handle for nucleophilic substitution reactions. This structure makes m-PEG6-Br an effective linker or intermediate for introducing PEGylation into small molecules, peptides, or other biomolecules. Its design minimizes steric hindrance and enhances biocompatibility, supporting applications in bioconjugation, drug delivery systems, and materials science. m-PEG6-Br is a useful building block for constructing PEG-modified compounds in chemical biology and pharmaceutical research.
