Mal-PEG3-CH2COOH CAS:518044-38-7 is a chemical compound used in bioconjugation and organic synthesis. It is a derivative of polyethylene glycol (PEG), a biocompatible polymer that is widely used in biomedical research. Mal-PEG3-CH2COOH is composed of a maleimide group, a PEG spacer consisting of three ethylene glycol units, and a carboxylic acid group. The maleimide group is a reactive site that can be used to attach Mal-PEG3-CH2COOH to thiol-containing biomolecules, such as proteins, peptides or antibodies, through a thiol-maleimide reaction. The carboxylic acid group provides a versatile site for further modification, allowing the creation of more complex compounds with specific properties. Mal-PEG3-CH2COOH is a valuable tool for drug delivery and bioconjugation research.
