The synthesis of heteroaromatic and aromatic compounds is at the heart of the chemical industry. The ever-growing demand for new chemical entities, coupled with dwindling resources and time constraints allotted to any given research project, a rapid way to diversify (hetero)aromatic scaffolds is needed.

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