Resorcinol BP Ph Eur Grade
Ph Eur
C6H6O2 --- 110.1 --- 108-46-3
Action and use: Keratolytic.
DEFINITION
Resorcinol contains not less than 98.5 per cent and not more than the equivalent of 101.0 per cent of benzene-1,3-diol, calculated with reference to the dried substance.
CHARACTERS
A colourless or slightly pinkish-grey, crystalline powder or crystals, turning red on exposure to light and air, very soluble in water and in alcohol.
IDENTIFICATION
A. Melting point:109C to 112C.
B. Dissolve 0.1 g in 1 ml of water add 1 ml of strong sodium hydroxide solution and 0.1 ml of chloroform, heat and allow to cool. An intense, deep-red colour develops which becomes pale yellow on the addition of a slight excess of hydrochloric acid.
C. Thoroughly mix about 10 mg with about 10 mg of potassium hydrogen phthalate, both finely powdered. Heat over a naked flame until an orange-yellow colour is obtained. Cool and add 1 ml of dilute sodium hydroxide solution and 10 ml of water and shake to dissolve. The solution shows an intense green fluorescence.
TESTS
Solution S: Dissolve 2.5 g in carbon dioxide-free water R and dilute to 25 ml with the same solvent.
Appearance of solution: Solution S is clear and not more intensely coloured than reference solution and remains so when heated in a water-bath for 5 min.
Acidity or alkalinity: To 10 ml of solution S add 0.05 ml of bromophenol blue solution. Not more than 0.05 ml of 0.1 M hydrochloric acid or 0.1 M sodium hydroxide is required to change the colour of the indicator.
Related substances: To pass the test
Pyrocatechol: To 2 ml of solution S add 1 ml of ammonium molybdate solution and mix. Any yellow colour in the solution is not more intense than that in a standard prepared at the same time in the same manner using 2 ml of a 0.1 g/l solution of pyrocatechol.
Loss on drying: Not more than 1.0 per cent, determined on 1.00 g of powdered substance by drying in a desiccator for 4 h.
Sulphated ash: Not more than 0.1 per cent, determined on 1.0 g.

Resorcinol USP Grade
C6H6O2 110.11
1,3-Benzenediol
Resorcinol [108-46-3].
Resorcinol contains not less than 99.0 percent and not more than 100.5 percent of C6H6O2, calculated on the dried basis.
Identification:
A: Infrared Absorption 197K NOTE—If necessary to recrystallize, dissolve in dehydrated alcohol.]
B: Dissolve 100 mg in 2 mL of 1 N sodium hydroxide, add 1 drop of chloroform, and heat the mixture: an intense crimson color is produced. Then add a slight excess of hydrochloric acid: the color changes to pale yellow.
C: To 10 mL of a solution (1 in 100) add 1 drop of ferric chloride: a blue-violet color is produced, and it fades slowly.
Melting range: between 109 and 111 .
Loss on drying: Dry it over silica gel for 4 hours: it loses not more than 1.0% of its weight.
Residue on ignition: not more than 0.05%.
Phenol: Heat gently a solution (1 in 20): the odor of phenol is not perceptible.
Catechol: To 10 mL of a solution (1 in 20) previously mixed with 2 drops of 1 N acetic acid add 0.5 mL of lead acetate: no turbidity is produced.
Ordinary impurities: To pass the test.
