General information

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.

Click Chemistry

In recent years, click chemistry has become increasingly important and steadily more popular in research and development. The reasons for this are not only the easy handling and the high yields but also the countless application possibilities. Carl ROTH offers you the possibility to purchase the broad portfolio of click reagents, various kits for EdU-based cell proliferation assays and numerous other applications from the well-known brand baseclick. This enables us to offer you a necessary and comprehensive assortment for click chemistry.

Nucleosides and Nucleotides


The detection of cell proliferation is of utmost importance for monitoring cell vitality, determining genotoxicity or evaluating anticancer drugs. The feeding of cells with EdU (5-Ethynyl-2'-deoxyuridine) or EU (5-Ethynyl uridine) can be used in cell proliferation studies.
