Properties

Description

Iodoacetamido-PEG3-t-butyl ester is a bifunctional PEG linker featuring an iodoacetamide group and a t-butyl ester-protected carboxyl group. The iodoacetamide acts as a strong alkylating agent, allowing for covalent binding with thiol groups, while the t-butyl ester provides acid-labile protection, facilitating controlled deprotection during synthesis.
