First Choice Coupling Reagent Kit

Product overview:

The amide coupling kits are ideal tools for the optimization of amide bond formation. This enables to conveniently screen multiple reaction conditions simultaneously using pre-weighed reagents. We offer pre-selected arrays of reagents and salts or custom arrays depending on your needs.

First choice array:

The first choice array contains a selection of the most representative coupling reagents from the 3 reagent classes; Carboddimide, Aminium and Phosphonium salts. We included ethyl (hydroxyimino)cyanoacetate) which can improve reaction rate. We can also create any custom array that would fit your needs.

Kit Description:

The kit contains vials loaded with 10 µmol of coupling reagent and a stirring bar and two vials containing ethyl (hydroxyimino)cyanoacetate). Reaction can be performed from 0.2 M in 50 µl to 0.05 M in 200 µl at 1/1 ratio acid and coupling reagent.
