Applications α-Propyl-α-(1-demethylethyl)-Verapamil is an impurity of Verapamil (V125000, HCl salt) which is a calcium channel blocker. References Atlas, D, and Adler, M.: Proc. Natl. Acad. Sci. USA, 78, 1237 (1981), Janis, R., et al.: Adv. Drug. Res., 16, 309 (1987)

Stability Hygroscopic, Light Sensitive, Temperature Sensitive Applications An intermediate in the Maillard reaction of proteins with glucose, which is metabolised to 3-Deoxyfructose. An intermediate in the formation of pyrraline, which might contribute to a pathological effect, such as carcinogenesis. References Kato, H. et al.: Agric. Biol.
