CHARACTERISTICS

IDENTIFICATION

Solubility(Vol. 4) Freely soluble in water, sparingly soluble in ethanol

Test for benzoate (Vol. 4) Passes test Use a 10% solution of the sample

Test for sodium(Vol. 4) Passes test

PURITY

Loss on drying(Vol. 4) Not more than 1.5% (105 , 4 h)

Acidity or alkalinity Dissolve 2 g of the sample, weighed to the nearest mg, in 20 ml of freshly

boiled water. Not more than 0.5 ml of either 0.1N sodium hydroxide or

0.1N hydrochloric acid should be required for neutralization, using

phenolphthalein TS as indicator.

Readily carbonizable Dissolve 0.5 g of the sample, weighed to the nearest mg, in 5 ml of

substances sulfuric acid TS. The colour produced should not be darker than a light

pink ( Matching Fluid Q\" )

Chlorinated organic Not more than 0.07% (as chlorine)

compounds (Vol. 4) Test 0.25 g of the sample using 0.5 ml of 0.01N hydrochloric acid in the

control

Readily oxidizable Add 1.5 ml of sulfuric acid to 100 ml of water, heat to boiling and add

substances 0.1N potassium permanganate, dropwise, until the pink colour persists for

30 sec. Dissolve 1 g of the sample, weighed to the nearest mg, in the

heated solution, and titrate with 0.1N potassium permanganate to a pink

colour that persists for 15 sec. Not more than 0.5 ml should be required.

Lead (Vol. 4) Not more than 2 mg/kg

Determine using an atomic absorption technique appropriate to the

specified level. The selection of sample size and method of sample

preparation may be based on the principles of the method described in

Volume 4, Instrumental Methods.

METHOD OF We oh, to the nearest mg, 3 g of the sample previously dried for 4 h at

ASSAY 105 and transfer to a 250-ml Erlenmeyer flask. Add 50 ml of water to

dissolve the sample. Neutralize the solution, if necessary, with 0.1N

hydrochloric acid, using phenolphthalein TS as indicator. Add 50 ml of

ether and a few drops of bromophenol blue TS, and titrate with 0.5N

hydrochloric acid, shaking the flask constantly, until the colour of the

indicator begins to change. Transfer the lower aqueous layer to another

flask. Wash the ethereal layer with 10 ml of water, and add the washing

and an additional 20 ml of ether to the separated aqueous layer.

Complete the titration with the 0.5N hydrochloric acid, shaking constantly

the flask.

Each ml of 0.5N hydrochloric acid is equivalent to 72.05 mg of C7 H5 NaO2
