Iodoform is the organoiodine compound with the formula CHI3. A pale yellow, crystalline, volatile substance, it has a penetrating and distinctive odor sometimes referred to as the smell of hospitals, sweetish taste. It is occasionally used as a disinfectant.
Iodoform USP Grade
or Triiodomethane
CHI3 393.73 [75-47-8].
Iodoform, previously dried over silica gel for 24 hours, contains not less than 99.0 percent and not more than 100.5 percent of CHI3.
Packaging and storage: Preserve in tight, light-resistant containers, store at controlled room temperature, and prevent exposure to excessive heat.
Identification: Heat 0.1 g: a purple gas is evolved.
Loss on drying: Dry it over silica gel for 24 hours: it loses not more than 0.5% of its weight.
Residue on ignition: not more than 0.1%.
Coloring matter, acids, and alkalies: Shake about 2 g of it with 5 mL of water for 1 minute, and filter: the filtrate is colorless and is neutral to litmus.
Chloride: Shake 3.0 g of powdered Iodoform with 75 mL of water for 1 minute, allow to stand, and filter the supernatant. To 25 mL of the filtrate add 6 mL of 3 N nitric acid, and dilute with water to 40 mL. This solution shows no more chloride than corresponds to 0.15 mL of 0.020 N hydrochloric acid (0.011%).
Sulfate: To 25 mL of the filtrate obtained in the test for Chloride add 1 mL of 3 N hydrochloric acid, and dilute with water to 40 mL. This solution shows no more sulfate than corresponds to 0.17 mL of 0.020 N sulfuric acid (0.017%).
Assay: Transfer about 200 mg of Iodoform, previously dried over silica gel for 24 hours and accurately weighed, to a 500-mL glass-stoppered conical flask. Add 20 mL of alcohol, and swirl to dissolve. Add 30.0 mL of 0.1 N silver nitrate and 10 mL of nitric acid, insert the stopper, and allow it to stand in a dark place for 16 hours. Add 150 mL of water and 5 mL of ferric ammonium sulfate and titrate the excess silver nitrate with 0.1 N ammonium thiocyanate. Perform a blank determination. Each mL of 0.1 N silver nitrate is equivalent to 13.124 mg of CHI3.
