Methyl-PEG3-bromide is a water-soluble, bench-stable reagent featuring a reactive bromide terminus and a hydrophilic PEG3 spacer. This compound enables efficient conjugation in aqueous media, facilitating the attachment of functional groups to biomolecules or surfaces without aggregation. Ideal for bioconjugation workflows requiring controlled chain length and enhanced solubility.
Methyl-PEG3-bromide serves as a versatile bifunctional linker for conjugation chemistry, enabling efficient attachment of PEGylated moieties to nucleophilic functional groups. Its terminal bromide facilitates reliable coupling with amines, thiols, and other soft nucleophiles under mild conditions, while the methyl terminus ensures stability and minimizes undesired side reactions. This reagent is widely used in the synthesis of PEGylated drug candidates, bioconjugates, and surface-modified nanoparticles due to its excellent solubility, predictable reactivity, and compatibility with standard synthetic workflows.
