Description
14-(Azide-PEG5-ethylcarbamoyl)tridecanoic t-butyl ester represents yet another PEG linker characterized by its inclusion of an azide group along with an alkane tail terminating with a t-butyl ester moiety. Like others mentioned before, this compound's azides are capable of reacting through click chemistry methods yielding stable triazole linkages while permitting deprotection of its protected carboxylic acid under mild acidic conditions.
