A chemical salt or compound formed by combining two picrate groups with a metal or organic base.
From di- (two) + picrate (a salt of picric acid). Picric acid was synthesized in the late 18th century, and dipicrate compounds were identified during 19th-century chemical studies.
Picric acid was once used as a yellow dye, but chemists realized it was also highly explosive—so dipicrates became important in studying unstable, energetic materials!
