DEFINITION
Sodium benzenecarboxylate
Content
99.0 per cent to 100.5 per cent (dried substance).
Appearance
White or almost white, crystalline or granular powder or flakes, slightly hygroscopic.
Solubility
Freely soluble in water, sparingly soluble in ethanol (90 per cent V/V).
IDENTIFICATION
A. It gives reactions of benzoates.
B. It gives reaction of sodium.
TESTS
Solution S
Dissolve 10.0 g in carbon dioxide-free water and
dilute to 100 ml with the same solvent.
Appearance of solution
Solution S is clear and not more intensely coloured
than reference solution.
Acidity or alkalinity
To 10 ml of solution S add 10 ml of
carbon dioxide-free
water and 0.2 ml of phenolphthalein solution. Not more than 0.2 ml of
0.1 M sodium hydroxide or 0.1 M hydrochloric acid is required to
change the colour of the indicator.
Halogenated compounds
Maximum 200 ppm for ionized chlorine and maximum 300 ppm
for total chlorine.
Sodium Benzoate USP NF
C7H5NaO2 144.10Benzoic acid, sodium salt.
Sodium Benzoate contains not less than 99.0 percent and not more than 100.5 percent of C7H5NaO2, calculated on the anhydrous basis.
Identification—
A: Infrared Absorption 197M , on the un-dried
specimen.
B: It responds to the tests for Sodium
and
for Benzoate.
Alkalinity— Dissolve 2 g in 20 mL of hot water, and
add 2 drops of phenolphthalein TS: 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%.
