We offer a comprehensive product range as building blocks for industries, research institutes and small amount for screening purposes. HetCat specialises in customer synthesis of heterocyclic compounds (5-, 6- and 7-membered rings having 1 and/or more N, O, S atoms in molecules), their metal complexes and catalysts. The unique heterocyclic compounds are very reactive ligands for formation of metal complexes, and form useful building blocks for medicinal chemistry. In addition, catalysts are widely applied in research and production. The chiral ones can be used in asymmetric synthesis. Normally, compounds are available in the range from 0.1 g - 500 g. On request, higher quantities are also available.
