Atropine is a tropane alkaloid used primarily as an anticholinergic medication to treat certain nerve agent exposures, heart rhythm disorders, and organophosphate poisoning. It blocks the action of the neurotransmitter acetylcholine, producing rapid heart rates, reduced secretions, and dilated pupils. This chemical has a CAS number of 51-55-8, molecular formula C17H23NO3, and a molecular weight of 289.37. It is stored at ambient conditions and carries a "Danger" signal word under GHS classification. Molekula supplies Atropine from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
