Introduction
Caffeine Anhydrous (CAS 58-08-2) is one of the most recognized and widely used Active Pharmaceutical Ingredients (APIs) globally. As a naturally occurring methylxanthine alkaloid, it is synthesized for pharmaceutical use to ensure the highest purity and consistency. In its anhydrous form, Caffeine is a white, odorless, crystalline powder with a bitter taste, serving as a powerful central nervous system (CNS) stimulant. This page provides technical insights and procurement specifications for pharmaceutical-grade Caffeine API.
