Properties

Description

N,N-diethanol amine-PEG4-tert-butyl ester is a PEG-based reagent featuring two hydroxyl groups and a t-butyl ester-protected carboxyl group. The hydroxyl groups provide nucleophilic sites for further functionalization, while the t-butyl ester can be selectively deprotected under mild acidic conditions. The PEG4 spacer enhances water solubility and biocompatibility, making it suitable for various chemical and biomedical applications.
