Advanced ceramic materials with a well-defined nano-architecture of their surfaces were formed by applying a two-step procedure. Firstly, a primary amine was docked on the ordered nanotubular ceramic surface via a silanization process. Subsequently, single-wall carbon nanotubes (SWCNTs) were covalently

Uronium and Guanidinium Salts

The special need of SPPS for rapid and highly efficient coupling reagents led to the development of several new reagents starting from BOP (Benzotriazol-1-yloxytris(dimethylamino)phosphonium hexafluorophosphate).

COMU-Safer and More Efficient Peptide Coupling Reagent

COMU is a non-explosive coupling agent suitable for solution phase & solid phase peptide synthesis. Its activity meets or exceeds that of HATU and its water-soluble by-product are easily removed.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
