TETRAMETHYLURIC ACID(Cas 2309-49-1) Usage

Uses

Tetramethyluric acid is an impurity of caffeine. Caffeine is a bitter, white crystalline xanthine alkaloid that acts as a stimulant drug and a reversible acetylcholinesterase inhibitor. Caffeine is found in varying quantities in the seeds, leaves, and fruit of some plants, where it acts as a natural pesticide that paralyzes and kills certain insects feeding on the plants. In humans, caffeine acts as a central nervous system stimulant, temporarily warding off drowsiness and restoring alertness. Caffeine is a cardiac and respiratory stimulant; diuretic. Caffeine is toxic at sufficiently high doses.

Purification Methods

Crystallise the uric acid from H2O or MeOH. [Beilstein 26 H 532, 26 I 156, 26 II 302, 21 III/IV 2623.]
