NHS-C3-Azide, 10 mg

Consumer Notice:

▶ aqueous media: copper(II) sulfate 7816, sodium ascorbate 7819, THPTA 7822▶ organic solvents (e.g. DMSO): Copper(I) bromide 7813, TBTA 7814 (copper stabilizing ligand)

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.

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.

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.

Linker

Click chemistry opens the door to introduce polyethylene glycols (PEGs) or other linkers in very sophisticated manner into your sample, which are still active for following reaction by the means of amine, carboxyl, malemide or NHS-functional terminal groups. You can choose between alkyne and azide structured PEGs and linkers which you find in the table below.
