Product details
All products identified as being particularly temperature-sensitive are shipped in special ice boxes with freezer packs or in dry ice.
Additional costs resulting from such, will be invoiced (further information on request).
Please note: In order to guarantee optimum product quality, the dispatch of refrigerated transport products will be carried out on Mon and Tue only outside Germany!
Slight delays in delivery are therefore possible.

General information
Vitamins are involved in many metabolic reactions. We can supply a range of high-purity substances suitable for biochemical applications in research and development.
TBTA (Art.No. 7814) is suitable as copper-stabilising ligand for reactions in organic solvents. THPTA (Art.No. 7822) on the other hand is an optimal ligand for reactions in aqueous media.
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.
