Application:	• Pharmacological agent used as muscarinic M3 antagonist for the inhaled treatment of chronic obstructive pulmonary disease (COPD)
Application:	(R)-(-)-3-Quinuclidinyl benzilate can be used as a reactant for the synthesis of quaternary ammonium derivatives of (3R)-quinuclidinol esters as potential muscarinic M3 antagonists. It can also be employed in the preparation of potent muscarinic cholinergic antagonist (R)-[N-methyl-3H]quinuclidinyl benzilate methiodide by alkylation with methyl iodide.
Biochem/physiol Actions:	Nonselective muscarinic acetylcholine receptor antagonist. More potent enantiomer of QNB.
Packaging:	5 mg in glass bottle
