Scopolamine

Scopolamine is a tropane alkaloid featuring a 8-methyl-8-azabicyclo[3.2.1]octane core with a 6,7-epoxy bridge and a 3-methylbutanoate ester substituent. The molecule contains a tertiary amine, an ether linkage, and a hydroxyl group on the tropane ring, conferring structural similarity to atropine but with a methyl substitution at the 6-position. As the parent drug, it exists in its free base form, distinct from salt derivatives. This compound serves as an HPLC reference standard for quantifying scopolamine in pharmaceutical formulations.
