Application Area

  • Medicinal Chemistry

    Medicinal Chemistry

    Medicinal chemistry and drug research require diverse chemical components to meet strict requirements not only in terms of physical and chemical properties but also in terms of chemical reactivity.

  • Organic Chemistry

    Organic Chemistry

    The chemists use the 'build–couple–pair' strategy of organic synthesis, which entails preparing molecular building blocks that contain several chemical groups.

  • Material chemistry

    Material chemistry

    The chemical building block (CBB) is a molecule which can be converted to various secondary chemicals and intermediates, and, in turn, into a broad range of different downstream uses.
