What is Isoindoline?

Description

Isoindoline can be considered as the “hydrogenated sister” of isoindole which is widespread in nature as heterocyclic core of alkaloids and antibiotics.

The Uses of Isoindoline

Isoindoline is used to make a chiral diamine catalyst from L-proline for the asymmetric acylation of alcohols.1

The Uses of Isoindoline

Isoindolinone and isoindoline pigments are high quality products. They are used in general and high grade industrial paints including original automobile and automotive refinishes, in plastics and for spin dyeing, and in high grade printing inks, especially for metal deco, laminated plastic sheets, and in printing inks for bank notes and securities.
