Optimize Your Copper-Catalyzed
Click Chemistry with Accelerating Ligands
Copper(I)-catalyzed Azide-Alkyne Click Chemistry (CuAAC) relies on the presence of Copper(I) ions (Cu⁺).
Cu⁺ ions are prone to oxidation which decreases the amount of active Cu⁺ available for reactions and leads to the formation of harmful byproducts which increase cytotoxicity in living cells. Ligands with tertiary amine and triazine groups stabilize Cu⁺ by protecting it from degradation thus boosting the efficiency of CuAAC reactions. In addition, the reduced toxicity improves compatibility with biological systems.
Vector offers a comprehensive portfolio of CuAAC accelerating ligands providing options to meet the unique needs of your azide-alkyne cycloaddition reactions: THPTA, BTTAA, BTTES, BTTP, and TBTA. Vector’s reagents are manufactured for exceptional quality, scalability, and reproducibility, with rigorous quality control ensuring dependable performance across a wide range of experimental applications.
