Benzuridine solution is primarily used in research settings for its pharmacological activity as a muscarinic receptor antagonist. It helps in studying cholinergic systems, particularly in neurological and cardiovascular research. Due to its ability to block specific acetylcholine receptors, it is applied in experiments analyzing smooth muscle contraction, glandular secretion, and autonomic nervous system regulation. Its solution form allows for precise dosing in in vitro and in vivo studies, making it valuable in preclinical drug development and mechanistic studies of receptor function.
