1,3-Benzenediol or Resorcinol

Resorcinol USP Grade
C6H6O2 -- 110.11
Resorcinol CAS 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.

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.
