Description
Azido-PEG11-t-butyl ester is a linker designed for click chemistry, featuring an azide (N3) and a t-butyl ester group. The hydrophilic PEG spacer enhances solubility in water-based environments. The azide moiety is reactive with alkynes, BCN, and DBCO through click chemistry methods. Additionally, the carboxylic acid protected by the t-butyl group can be deprotected under acidic conditions.
