Properties

Description

Iodoacetamido-PEG8-t-butyl ester is a bifunctional PEG reagent featuring an iodoacetamide group and a t-butyl ester-protected carboxyl group. The iodoacetamide acts as a potent alkylating agent, capable of forming stable covalent bonds with thiol groups, while the t-butyl ester provides temporary protection that can be removed under acidic conditions.
