Potassium Benzoate or Benzoic Acid Potassium Salt
CAS Number: 582-25-2
Molecular Formula: C7H5KO2
Molecular Weight: 160.21
Potassium Benzoate or Benzoic Acid Potassium Salt
Potassium Benzoate USP NF Grade Specifications
C7H5KO2 160.21
Benzoic acid, potassium salt.
Potassium benzoate CAS 582-25-2
Potassium Benzoate contains not less than 99.0 percent and not more than 100.5 percent of C7H5KO2, calculated on the anhydrous basis.
Identification: It responds to the flame test for Potassium and to the tests for Benzoate.
Alkalinity: Dissolve 2 g in 20 mL of hot water, and add 2 drops of PhPh: the pink color produced, if any, is discharged by the addition of 0.20 mL of 0.10 N sulfuric acid.
Water: not more than 1.5%.
Heavy metals: the limit is 0.001%.
Assay: Transfer about 600 mg of Potassium Benzoate, accurately weighed, to a 250-mL beaker. Add 100 mL of glacial acetic acid, stir until the assay specimen is completely dissolved, add 2 drops of crystal violet and titrate with 0.1 N perchloric acid. Perform a blank determination, and make any necessary correction. Each mL of 0.1 N perchloric acid is equivalent to 16.02 mg of C7H5KO2.
