Caffeine

Description:

Caffeine, with the CAS number 58-08-2, is a naturally occurring stimulant belonging to the xanthine class of compounds. It is primarily found in coffee beans, tea leaves, and cacao pods. Caffeine is a white, odorless crystalline powder that is soluble in water and has a slightly bitter taste. Its molecular formula is C8H10N4O2, and it has a molecular weight of approximately 194.19 g/mol. Caffeine acts as a central nervous system stimulant, temporarily warding off drowsiness and restoring alertness. It works by blocking the action of adenosine, a neurotransmitter that promotes sleep, thereby increasing the release of other neurotransmitters like dopamine and norepinephrine. Caffeine is commonly consumed in beverages such as coffee, tea, and energy drinks, and it is also available in various pharmaceutical formulations. While moderate consumption is generally considered safe for most individuals, excessive intake can lead to side effects such as insomnia, jitteriness, and increased heart rate.

Impurity Pentoxifylline EP Impurity F
Applications Caffeine (Pentoxifylline EP Impurity F) is a bitter, white crystalline xanthine alkaloid that acts as a stimulant drug and a reversible acetylcholinesterase inhibitor (1,2,3). 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. Caffeine is a non-competitive inhibitor of acetylcholinesterase (3).This compound is a contaminant of emerging concern (CECs).
Not a dangerous good if item is equal to or less than 1g/ml and there is less than 100g/ml in the package
