Description
Caffeine is a stimulant drug that occurs naturally in certain plants and fruits. Most commonly extracted from the seed of the coffee plant, this white crystalline xanthine alkaloid has a bitter taste and acts on the central nervous system as a stimulant, reducing drowsiness and increasing alertness. It is an achiral molecule that has no stereoisomers. Ungraded products supplied by TCI America are generally suitable for common industrial uses or for research purposes but typically are not suitable for human consumption or therapeutic use.
