M-PEG-aldehyde is a polyethylene glycol derivative with an aldehyde functional group located at its terminal end. The aldehyde group allows for easy conjugation with amino groups, making it a useful reagent in pharmaceutical research and development.

In drug development, M-PEG-aldehyde is commonly used for the functionalization of proteins, peptides, and other biologically active molecules. The resulting conjugates can improve the solubility, stability, and pharmacokinetic properties of the original molecule, as well as enhance its targeting and delivery to specific tissues or cells.

Moreover, M-PEG-aldehyde has been employed as a linker or spacer molecule to connect two or more molecules together. This strategy can be used to create prodrugs, which are inactive forms of a drug that can be converted to the active form by enzymatic or chemical cleavage.

M-PEG-aldehyde is a versatile reagent with important applications in drug discovery and development. Its unique aldehyde functional group allows for easy conjugation and functionalization of biomolecules, and its use as a linker or spacer molecule can lead to the development of novel prodrugs with improved properties.
