BISMUTH SUBCITRATE POTASSIUM

Bismuth Subcitrate potassium is an antibiotic used to treat stomach ulcers infected with Helicobacter pylori.

Bismuth Subcitrate potassium crystallizes in dilute HCl at pH 3, a unique assembly of three basic bismuth citrate dimer units ([Bi(cit)2Bi]2-) forming two-dimensional sheets and three-dimensional polymers , found that the solubility of Colloidal Bismuth Subcitrate in water was greatly affected by pH, from above 70 mg/mL at pH 7, down to 1 mg/mL at pH 3.
