Molecular Weight: 122.1
Benzoic Acid USP
C7H6O2 -- 122.12
Benzoic acid CAS 65-85-0
Benzoic Acid contains not less than 99.5 percent and not more than 100.5 percent of C7H6O2, calculated on the anhydrous basis.
Identification: Prepare a saturated solution of Benzoic Acid in water, and filter twice. To one portion of the filtrate add ferric chloride TS: a salmon-colored precipitate is formed. To a separate 10-mL portion of the filtrate add 1 mL of 7 N sulfuric acid and cool the mixture: a white precipitate forms in about 10 minutes; this precipitate is soluble in ether.
Congealing range: between 121 and 123.
Water: not more than 0.7%, a 1 in 2 solution of methanol in pyridine being used as the solvent.
Readily carbonizable substances: Dissolve 500 mg in 5 mL of sulfuric acid TS: the solution has no more color than Matching Fluid Q.
Residue on ignition: not more than 0.05%.
Heavy metals: Dissolve 2.0 g in 25 mL of acetone, and add 2 mL of water. Add 1.2 mL of thioacetamide-glycerin base TS and 2 mL of pH 3.5 Acetate Buffer, and allow to stand for 5 minutes: any color produced is not darker than that of a control made with 25 mL of acetone, 2.0 mL of Standard Lead Solution, and treated in the same manner. The limit is 10µg per g.
Readily oxidizable substances: Add 1.5 mL of sulfuric acid to 100 mL of water, heat to boiling, and add 0.1 N potassium permanganate, drop wise, until the pink color persists for 30 seconds. Dissolve 1.00 g of Benzoic Acid in the hot solution, and titrate with 0.1 N potassium permanganate to a pink color that persists for 15 seconds: not more than 0.50 mL of 0.10 N potassium permanganate is consumed.
Benzoic Acid FCC Food Grade
C7H6O2 Formula weight 122.12
INS: 210 CAS 65-85-0
Benzoic Acid occurs as white crystals, scales, or needles. It begins to sublime at about 100° and is volatile with steam. One gram is soluble in 275 mL of water at 25°, in 20 mL of boiling water, in 3 mL of alcohol, in 5 mL of chloroform, and in 3 mL of ether. It is soluble in fixed and in volatile oils and is sparingly soluble in hexane.
Identification: Dissolve 1 g of sample in a 20:1 (v/v) mixture of water and 1 N sodium hydroxide, filter the solution, and add about 1 mL of ferric chloride TS. A buff-colored precipitate forms.
Assay: Not less than 99.5% and not more than 100.5% of C7H6O2, calculated on the anhydrous basis.
Lead: Not more than 2.0 mg/kg.
Readily Carbonizable Substances: Passes test.
Readily Oxidizable Substances: Passes test.
Residue on Ignition: Not more than 0.05%.
Solidification Point: Between 121-123C.
Water: Not more than 0.7%.
