Strain-Promoted Click Chemistry
This reagent facilitates the strain-promoted, copper-free click chemistry (SPAAC) reaction with 1,2,4,5-tetrazines. The 4+2 inverse electron demand Diels-Alder cycloaddition is catalytically free and results in a stable covalent linkage.
Biomolecule Labelling and Imaging
The rapid and bio-orthogonal nature of the reaction makes it ideal for labelling and imaging of biomolecules in biological systems. It allows for the attachment of the cyclooctene functionality to amine-containing biomolecules.
Conjugation Chemistry
As a succinimidyl carbonate, it is designed to react with primary amines, enabling the conjugation of the cyclooctene handle to peptides, proteins, or other amine-functionalized molecules for further functionalization.

| Application | Succinimidyl carbonate/NHS functionalized cyclooctene derivative for incorporation of the cyclooctene moiety into amine containing compounds or biomolecules. Cyclooctenes are useful in strain-promoted copper-free click chemistry cycloaddition reactions with 1,2,4,5-tetrazines. This cyclooctene will react with tetrazine functionalized compounds or biomolecules without the need for a catalyst to result in a stable covalent linkage. The 4+2 inverse electron demand Diels-Alder cycloaddition between trans-cyclooctene and tetrazines is the fastest biologically compatible ligation technology reported and has had many applications in biological labeling and imaging. |
