Herein, we describe the syntheses and characterization of process related impurities of anti-vertigo drug betahistine dihydrochloride. We have identified seven impurities during the synthesis of betahistine dihydrochloride from 2-pyridineethanol. Among that, four impurities such as N-acetyl betahistine, 2-(pyridine-2-yl)ethyl acetate, N-methyl betahistine and N-methyl-2-(pyridine-2-yl)prop-2-en-1-amine are not reported in the literature. In this article, we describe the origin, syntheses and characterization of three of these unspecified impurities.
