"baseclick-grade" copper catalyst in high quality for optimal yield
Copper(I) bromide (CuBr) is a source of a click-active copper species. In organic solvents it works optimal with TBTA as a ligand. Our CuBr is of high purity and we take especially care for its stability. In this state it is one of the most effective catalyst for click reactions. After solubilizing it is necessary to use it right away to avoid fast degradation (< 30 min).

Reagents for Click Chemistry

Starting from diverse copper catalyst sources, over Cu(I) stabilising ligands to buffer additives and solvents, you will find all necessary reagents in the special ROTI®Click quality to perform your click reactions here.


Click Chemistry

The copper(I)-catalysed azide-alkyne cycloaddition (CuAAC) is the most prominent example of a group of reactions named click reactions. According to Sharpless’ definition, these reactions are characterised by high yields, mild reaction conditions, and by their tolerance of a broad range of functional groups.[1-3] Typically, the reactions require simple or no workup or purification of the product. The most important characteristic of the CuAAC reaction is its unique bioorthogonality as neither azide nor terminal alkyne functional groups are generally present in natural systems.
