Caffeine is a bitter, white crystalline methylxanthine alkaloid and purine derivative, structurally related to adenine and guanine. It occurs naturally in various plant sources, notably coffee beans, and can be commercially synthesized from dimethylurea and cyanoacetic acid. Pharmacologically, caffeine is primarily known for its effects on mental alertness and is investigated for other applications including headache, migraine, and athletic performance.
