Benzenemethanol.
[100-51-6].
Benzyl Alcohol contains not less than 98.0 percent and not more than 100.5 percent of C7H8O.
Labeling— Where Benzyl Alcohol is intended for use in the manufacture of injectable dosage forms, it is so labeled.
Clarity
of solution—
Test solution— Dissolve 2.0 g of Benzyl Alcohol in 60 mL of water, and mix.
To pass the test as per monograph
The Test solution shows the same clarity as that of water, or its
opalescence is not more pronounced than that of Reference suspension.
Color of
solution—
Test solution— Use the Test solution prepared in the test for
Clarity of solution.
To pass the test as per monograph
Test solution
has the color of water.
Identification— Infrared Absorption
197F , on un-dried specimen.
Peroxide
value: not more than 5.
Refractive index: between 1.538 and 1.541 at 20.
Acidity— Neutralize 50 mL of alcohol containing 1 mL of phenolphthalein TS with 0.10
N sodium hydroxide. Dissolve 10 mL of Benzyl Alcohol in 10 mL of the neutralized
alcohol, and titrate with 0.10 N sodium hydroxide to the first appearance of a
pink color that persists for not less than 30 seconds: not more than 1.0 mL is
consumed.
Limit of
nonvolatile residue— [NOTE—Ensure that the Benzyl Alcohol to be examined
complies with the test for Peroxide value before performing this test.]
Evaporate 10.0 g of Benzyl Alcohol on a water bath to dryness, and dry the
residue at 105 for 1 hour. Cool in a desiccator, and weigh. The residue weighs
not more than 5 mg: not more than 0.05% of nonvolatile residue is found.
