Sigma Aldrich Fine Chemicals Biosciences Caffeine anhydrous 99 fCC25KG
Caffeine is an addictive psychoactive compound consumed mostly in the form of brewed coffee instant coffee tea and caffeinated soft drinks. Caffeine is reported to be an allergen and causes anaphylaxis. It is added to common analgesics such as paracetamol ibuprofen and aspirin for enhancing their analgesic efficacy. It is a plant-derived drug and has been detected in low doses in the floral nectar and pollen of Citrus. Determination of caffeine in beverages by square-wave voltammetry using Nafion-ruthenium oxide pyrochlore chemically modified electrode has been reported. Caffeine acts as an antagonist of adenosine A1 receptors (A1R) and A2AR at non-toxic doses. Chronic consumption of caffeine is reported to prevent the memory impairment in type 2 diabetic mice.
