Definition
Adjective (Chemistry): - Relating to or derived from barbituric acid, a crystalline compound (C₄H₄N₂O₃) that is the parent substance of barbiturate drugs. Barbituric acid itself is not a sedative but serves as a chemical base for synthesizing barbiturates.
Usage Examples
- (Describing the chemical substance used to create barbiturates.)
- (Referring to compounds chemically related to barbituric acid.)
