Nortropine

CAS 538-09-0

Nortropine (CAS 538-09-0) illustrates how molecular structure determines chemical role. Nortropine (CAS 538-09-0) is a tropane alkaloid framework closely related to tropine but lacking the N-methyl group; its name literally reflects this 'nor' relationship. The bicyclic tropane skeleton is historically important because it forms the core of natural alkaloids such as atropine and scopolamine and of numerous semisynthetic derivatives. Nortropine contains a secondary amine and an alcohol, giving chemists two distinct functional sites for N-substitution and O-acylation or related transformations. Removing or changing the nitrogen substituent is a common medicinal-chemistry strategy for exploring how charge, lipophilicity, and receptor interactions change across tropane derivatives. Public records for nortropine emphasize its role as a chemical and pharmaceutical intermediate rather than an independently used therapeutic drug.
