2,5-Dimethyl pyrazine Chemical Properties,Uses,Production

Chemical Properties

clear colorless to pale yellow liquid

Uses

Used for blending food, nuts and beverage flavors.

Safety Profile

Moderately toxic by ingestion and intraperitoneal routes. Mutation data reported. When heated to decomposition it emits toxic fumes of NOx

Purification Methods

Purify it via its picrate (m 150o) which is decomposed with a base (e,g, KOH) and distilled. [Wiggins and Wise J Chem Soc 4780 1956]. [Beilstein 23/5 V 403.]
