カフェイン 化学特性,用途語,生産方法

化学的特性 white to light yellow crystal powder 使用 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. 使用 CNS stimulant respiratory stimulant;adenosine receptors antagonist 一般的な説明 Odorless white powder or white glistening needles, usually melted together. Bitter taste. Solutions in water are neutral to litmus. Odorless. 空気と水の反応 Efflorescent in air. Water soluble. 反応プロフィール Caffeine may be hygroscopic. Aqueous solutions (1.12 mg/mL) are stable for three weeks at 41° F if protected from light. In normal room lighting and at room temperature, solutions are stable for 3 days. Solutions of Caffeine in water, DMSO, 95% ethanol or acetone should be stable for 24 hours under normal lab conditions. REACTIVITY: Caffeine may react with strong oxidizing agents. Caffeine is also incompatible with iodine, silver salts and tannins. Caffeine is a very weak base. Caffeine is decomposed by strong solutions of caustic alkalis. 火災危険 Flash point data for Caffeine are not available; however, Caffeine is probably combustible. 生物活性 Central nervous system stimulant. Antagonist at A 1 and A 2A adenosine receptors and inhibitor of cyclic nucleotide phosphodiesterases. Mobilises calcium from intracellular stores and inhibits benzodiazepine binding to GABA receptors.
