(Official until July 1, 2007)
Assay— Dissolve about 200 mg of Sodium Propionate, previously dried at 105 for 2 hours and accurately weighed, in 50 mL of glacial acetic acid. Add 1 drop of crystal violet TS, and titrate with 0.1 N perchloric acid VS to a green endpoint. Perform a blank determination, and make any necessary correction. Each mL of 0.1 N perchloric acid is equivalent to 9.606 mg of C3H5NaO2.

Function: Preservative; mold inhibitor.

REQUIREMENTS
Identification:
A. A 1:20 aqueous solution gives positive tests for Sodium.
B. Upon ignition, a sample yields an alkaline residue that effervesces with acids.
C. Warm a small sample with sulfuric acid. Propionic acid, recognized by its odor, evolves.
