Mal-propionylamido-PEG7-acetic acid is a bifunctional, water-soluble, and biocompatible reagent with wide-ranging applications in pharmaceutical research and development. This versatile molecule features two distinct functional groups: the maleimide (Mal) moiety, which readily reacts with sulfhydryl-containing compounds (e.g., cysteine residues in proteins), and the carboxylic acid (Ac) group, which can be conjugated to primary amines (e.g., lysine residues) via amide bond formation.
The presence of a polyethylene glycol (PEG7) spacer imparts increased hydrophilicity and flexibility to the linker, enhancing solubility and minimizing steric hindrance between coupled molecules. Consequently, Mal-propionylamido-PEG7-acetic acid facilitates the formation of stable, bioactive conjugates in applications such as drug delivery, targeted therapeutics, and bioconjugate chemistry.
