Ethacrynic acid is an unsaturated ketone derivative of an aryloxyacetic acid. It is designated chemically as [2,3-dichloro-4-(2-methylene-1-oxobutyl)phenoxy] acetic acid, and has a molecular weight of 303.14. Ethacrynic acid is a white, or practically white, crystalline powder, very slightly soluble in water, but soluble in most organic solvents such as alcohols, chloroform, and benzene. Its empirical formula is C 13 H 12 Cl 2 O 4 and its structural formula is: Ethacrynate sodium, the sodium salt of ethacrynic acid, is soluble in water at 25°C to the extent of about 7 percent. Solutions of the sodium salt are relatively stable at about pH 7 at room temperature for short periods, but as the pH or temperature increases the solutions are less stable. The molecular weight of ethacrynate sodium is 325.12. Its empirical formula is C 13 H 11 Cl 2 NaO 4 and its structural formula is: Intravenous Ethacrynate Sodium is a sterile freeze-dried powder and is supplied in a vial containing: Ethacrynate sodium equivalent to ethacrynic acid - 50 mg Inactive ingredient: Mannitol - 62.5 mg chemicalstructure chemicalstructure1
