Apexbio Technology LLC Tolazoline HCl 59-97-2 1g
Tolazoline hydrochloride (CAS 59-97-2) is a small molecule that functions as a competitive antagonist at -adrenergic receptors exhibiting non-selective affinity for both 1- and 2-adrenoceptor subtypes By inhibiting endogenous catecholamine binding tolazoline modulates vasomotor tone and vascular smooth muscle contraction This pharmacological profile enables researchers to investigate adrenergic signaling pathways and the physiological roles of -adrenergic receptors Tolazoline HCl is widely utilized in studies of vascular function receptor pharmacology and the characterization of sympathetic nervous system mechanisms
