1,8-Naphthalic anhydride Chemical Properties,Uses,Production

Chemical Properties

BEIGE TO LIGHT BROWN POWDER

Uses

1,8-Naphthalic anhydride is used as a seed protectant and to prepare dyestuffs and optical brighteners. It is used in the preparation of napthalimide analogues, which finds application as anticancer agents. Further, it is used as fluorescent brightening agent for polymeric materials.

Purification Methods

Extract it with cold aqueous Na2CO3 to remove free acid, then crystallise from acetic anhydride. [Beilstein 17 III/IV 6392, 17/11 V 492.]
