I. [Product Description]
BSA-PEG-Br (Bromide) is a functionalized bromide based on the covalent modification of bovine serum albumin (BSA) and polyethylene glycol (PEG). It has both biocompatibility and chemical modifiability, and can be used as an **organic intermediate** or **pharmaceutical intermediate** in the bioconjugation reaction system. Its brominated terminal group can serve as an efficient **catalyst** or reaction site, and is suitable for molecular design and functional modification in multiple fields.
