m-PEG-PA(Methoxy PEG propionic acid) is a highly effective, water-soluble and biocompatible polymer, widely utilized in pharmaceutical research and development. This versatile compound is characterized by a methoxy-terminated polyethylene glycol (mPEG) chain and a carboxylic acid functional group (PA), resulting in a unique amphiphilic nature that imparts exceptional solubilizing and stabilizing properties to the molecule.

The mPEG segment offers stealth characteristics, reducing immunogenicity and prolonging circulation times, while the propionic acid moiety provides an accessible site for conjugation to a variety of biomolecules, including peptides, proteins, and small molecule drugs. This allows the creation of innovative drug delivery systems, prodrugs, and targeted therapeutics, enhancing bioavailability and reducing toxicity.

m-PEG-PA plays a crucial role in the development of novel biopharmaceuticals, including PEGylated proteins and peptide-drug conjugates, and serves as a valuable tool in the design of advanced drug carriers such as micelles, liposomes, and hydrogels.
