Furosemide (CAS NO.54-31-9) is used as a diuretic and blood pressure reducer and it is sometimes used in the management of severe hypercalcemia in combination with adequate rehydration. As a loop diuretic, Furosemide is used in the treatment of congestive heart failure and edema. Besides, it has also been used to prevent thoroughbred and standardbred race horses from bleeding through the nose during races. And along with some other diuretics, Furosemide(54-31-9) is also included on the World Anti-Doping Agency's banned drug list because of its alleged use as a masking agent for other drugs.
Furosemide (CAS NO.54-31-9) is prepared by treating 2,4,5-trichlorobenzoic acid with chlorosulfonic acid, and fur-ther treatment with ammonia and furfuryl amine. Furosemide can also be synthesized stating with 2,4-dichlorobenzoic acid (formed by chlorination and oxidation of toluene). Reaction with chlorosulfonic acid is an electrophilic aromatic substitution via the species -SO,Cl- attacking ortho and para to the chlorines and meta to the carboxylate. Ammonolysis to the sulfonamide is followed by nucleophilic aromatic substitution of the loss hindered chlorine by furfurylamine (obtained from furfural-a product obtained by the hydrolysis of carbohydrates).
