MPEG Thiolactote is a monofunctionalized polyethylene glycol (PEG) derivative, consisting of a methoxy end, a polyethylene glycol chain, and a thiolactate end. This compound can form thiol groups (- SH) through ring opening under mild conditions. Thiol groups have high reactivity and can covalently bind with molecules such as gold nanoparticles and proteins, achieving biological coupling or chemical modification. Its good water solubility and biocompatibility make it widely used in protein modification (such as PEGylation), drug delivery systems (such as nanocarrier functionalization), and surface modification of biomaterials. During storage, avoid exposure to light and moisture, and maintain a low temperature and dry environment.

【 Application Fields 】

Based on its mild and efficient coupling ability, it is mainly used for:

PEGylation modification of proteins/peptides: Site directed modification of primary amino groups under physiological conditions to improve the pharmacokinetic properties of drugs and reduce immunogenicity.

Functional nanocarrier construction: used to modify liposomes, polymer nanoparticles, etc., by introducing a PEG "invisible" layer and endowing the surface with further reactive thiol groups.

Material surface modification: Introducing thiol groups onto the surface of metal nanoparticles or polymer materials to achieve stable functionalization.

Polymer synthesis: as an organic intermediate, used to prepare more complex functional polymer materials
