Dahlund, Mats; Olin, Aake published the artcile< An estimate of the complexing ability of olsalazine from a study of its complexation of copper(2+)>, Recommanded Product: Sodium 5,5′-(diazene-1,2-diyl)bis(2-hydroxybenzoate), the main research area is olsalazine complexation copper.
The di-Na salt of olsalazine, Na2H2A, is the essential component in a new drug for the treatment of ulcerative colitis. An attempt was made to elucidate the complex chem. of H2A2- from a study of its complexation of Cu2+. The values of the equilibrium constants were β1 = 1.3 x 10-2 and β2 = 3 x 10-5 (25°, 0.1M NaNO3) as determined by spectrophotometric measurements. The value of β1 is discussed with reference to the corresponding value for salicylic and 5-sulfosalicylic acid. The formation constants of metal complexes of H2A2-, which in general are difficult to determine, can be estimated from the known values for 5-sulfosalicylic acid.
