Properties

Description

Azido-PEG3-S-PEG4-t-butyl ester is a reagent grade PEG linker with a t-butyl-protected carboxyl group and an azide group. The PEG spacer increases water solubility. Under standard acid/amine or acid/hydroxyl coupling conditions, the t-butyl-protected carboxyl group (COOH) prevents self-coupling or polymerization.
