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. 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.
