1,8-Naphthalic anhydride Chemical Properties,Uses,Production
Chemical Properties
BEIGE TO LIGHT BROWN POWDER
Uses
Dyestuffs, organic synthesis in general.
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.
Definition
ChEBI: Naphthalic anhydride is a cyclic dicarboxylic anhydride.
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.]
