6-Azido-hexanoic acid

Description

6-Azido-hexanoic acid is a linker containing an azide group and a terminal carboxylic acid. The azide group can react with alkyne, BCN, DBCO via Click Chemistry to yield a stable triazole linkage. The terminal carboxylic acid can react with primary amine groups in the presence of activators (e.g. EDC, or HATU) to form a stable amide bond.

The Uses of 6-Azido-hexanoic acid

6-Azidohexanoic acid is a six-carbon saturated fatty acid with an ω-terminal azide group. This building block can be reacted with primary amine groups in the presence of activators (e.g. EDC, or DCC), forming a stable amide bond. The terminal azide group allows conjugation with compounds containing alkyne groups through a copper(I)-catalyzed cycloaddition reaction, also known as click chemistry. 6-Azidohexanoic acid is useful for crosslinking, synthesis of chemical probes, and other bioconjugation strategies.
