3-Oxa-7-azabicyclo[3.3.1]nonan-9-ol hydrochloride

3‑oxa‑7‑azabicyclo[3.3.1]nonan‑9‑ol hydrochloride (CAS: 2555249‑91‑5) is a rigid bicyclic heterocycle featuring an oxygen and nitrogen ring. It serves as:

• A structural scaffold for medicinal chemistry, particularly in designing receptor-selective molecules (e.g., κ‑opioid receptor ligands).

• A versatile pharmaceutical intermediate for incorporating rigid bicyclic units into drug molecules.

• A research-grade chemical reagent, commonly found in CRO/CDMO R&D libraries, with typical purity of ~97%
