Use of n-methyldopamine hydrochloride

N-Methyldopamine hydrochloride is a precursor of adrenaline in the adrenal medulla. N-Methyldopamine hydrochloride is a modification of the dopamine (DA), and retains agonist activity at the DA1 receptor. N-Methyldopamine hydrochloride remains capable of universal surface coating and secondary reactions using the surface catechols. N-Methyldopamine hydrochloride can be used for heart failure research[1][2][3].
