Biotin alkyne is a biotinylated compound that enables simple biotinylation of antibodies, proteins and any other azide-containing biomolecules. The alkyne group of this reagent can react with azide moiety in Cu(I)-catalyzed Click Chemistry reaction to form a stable triazole linkage.

Biotin alkyne is a PEG-based PROTAC linker that can be used in the synthesis of PROTACs[1]. Biotin alkyne is a click chemistry reagent, it contains an Alkyne group and can undergo copper-catalyzed azide-alkyne cycloaddition (CuAAc) with molecules containing Azide groups.
