Identification—
A: Infrared Absorption on the undried specimen.
B: A solution (1 in 10) meets the requirements of the tests for Sodium..
Alkalinity: Dissolve 2.0 g in 20 mL of water, and add 1 drop of phenolphthalein TS: if a pink color is produced, it is discharged by 0.50 mL of 0.10 N sulfuric acid.
Water: not more than 1.0%.
Heavy metals: 0.001%.
Assay: Dissolve about 200 mg of Sodium Butyrate, accurately weighed, in 50 mL of glacial acetic acid. Add 1 drop of crystal violet TS, and titrate with 0.1 N perchloric acid to a green endpoint. Perform a blank determination, and make any necessary correction. Each mL of 0.1 N perchloric acid is equivalent to 11.01 mg of C4H7NaO2.
