Synthetic Strategy for Large Scale Production of Oligothiophenes

Oligothiophenes are important organic electronic materials which can be produced using synthetic intermediates and Suzuki coupling.

Boronic Acid Esters

The synthesis of biaryl compounds via the Suzuki–Miyaura coupling reaction has become more commonplace now that many arylboronic acids are readily available.

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