Caffeina

Descrizione:

Caffeina, con il numero CAS 58-08-2, è uno stimolante di origine naturale appartenente alla classe dei composti xantina. Si trova principalmente nei chicchi di caffè, nelle foglie di tè e nei baccelli di cacao. Caffeina è una polvere cristallina bianca e inodore che è solubile in acqua e ha un sapore leggermente amaro. La sua formula molecolare è C8H10N4O2 e ha un peso molecolare di circa 194,19 g/mol. Caffeina agisce come uno stimolante del sistema nervoso centrale, allontanando temporaneamente la sonnolenza e ripristinando la vigilanza. Funziona bloccando l'azione dell'adenosina, un neurotrasmettitore che promuove il sonno, aumentando così il rilascio di altri neurotrasmettitori come dopamina e norepinefrina. Caffeina è comunemente consumato in bevande come caffè, tè e bevande energetiche, ed è disponibile anche in varie formulazioni farmaceutiche. Sebbene il consumo moderato sia generalmente considerato sicuro per la maggior parte delle persone, un'assunzione eccessiva può portare a effetti collaterali come insonnia, nervosismo e aumento della frequenza cardiaca.

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
