PEG-t-butyl ester(t-butyl ester-PEG Linkers), also known as tert-butyl polyethylene glycol, is a versatile chemical compound that is commonly used in pharmaceutical research and development. It is a derivative of polyethylene glycol (PEG) that has been modified with a tert-butyl ester group, which provides improved solubility and stability properties.

PEG-t-butyl ester has a wide range of applications in the pharmaceutical industry, including drug delivery, protein conjugation, and surface modification of drug particles. It is particularly useful in the formulation of poorly soluble drugs, where it can enhance their solubility and bioavailability.
