Harmonized System
3-Quinuclidinol is a bicyclic tertiary alcohol used as a pharmaceutical intermediate, most notably in the synthesis of certain anticholinergic and antispasmodic drug compounds. It is also listed as a scheduled precursor chemical under the Chemical Weapons Convention (CWC) due to its structural relationship to certain nerve agent antidotes and precursors, which subjects imports to additional regulatory scrutiny beyond standard CBP entry. India and Germany are the leading US suppliers, reflecting both generic API manufacturing capacity and European specialty chemical production.

3-Quinuclidinol is a Schedule 2 chemical under the CWC because it is a precursor to BZ (3-quinuclidinyl benzilate), an incapacitating agent. This means importers may be subject to declaration and reporting obligations under the Chemical Weapons Convention Implementation Act, administered through the Commerce Department's Bureau of Industry and Security (BIS), in addition to standard CBP entry requirements. Consult a licensed customs broker and export-control counsel before importing.
The primary commercial use is as a chiral building block in the synthesis of anticholinergic drugs and certain antiemetic compounds. Its rigid bicyclic scaffold provides a defined spatial geometry that medicinal chemists use to achieve receptor selectivity, making it a valued intermediate for specialty pharmaceutical manufacturers despite its relatively low trade volume.
