t-Butyl Acetate-PEG8-t-Butyl Acetate Product Description
This compound is a derivative of polyethylene glycol (PEG8) modified with t-butyl ester groups at both ends. Its molecular structure is linear, featuring t-butyl ester groups (-COO-tBu) at each terminus and eight repeating ethylene glycol units (-CH₂CH₂O-) in between, with an approximate molecular weight of 600. It is typically produced via esterification using octaglycol as the starting material, where t-butyl protecting groups are reacted to introduce the terminal esters. Strict temperature control (<140°C) and inert gas protection are required during synthesis to prevent polymerization.
As a key linker in PROTAC technology, its hydrophilic PEG chain enhances molecular solubility. The t-butyl ester groups can be deprotected under acidic conditions to release active carboxyl groups. This compound is widely used in the design and synthesis of targeted protein degradation drugs, particularly showing application potential in cancer therapy.
