	NTP: Abstract for TR-110 Iodoform
		Iodoform, a halogenated alkane with antiseptic and anti-infective properties, was selected for bioassay by the National Cancer Institute because of its similarity to methyl iodide, which has produced sarcomas in BD rats and to chloroform, a compound which has been found to induce hepatomas in NLC mice.
		Iodoform in corn oil was administered by gavage, at either of two dosages, to groups of 50 male and 50 female animals of each species.
		The high and low time-weighted average dosages of iodoform were, respectively, 142 and 71 mg/kg/day for male rats, 55 and 27 mg/kg/day for female rats, and 93 and 47 mg/kg/day for male and female mice.

		Iodoform precipitates as yellow crystalls, those are filtered after 30 minutes, washed with small ammount of water and air dryed.
		On second thoughts - it looks like the properly washed iodoform is not as lachrymatory - instead this property was probably caused by intial reaction products that were present in the supernatant - I imagine iodoacetone, a close relative to the well-known lachrymator chloroacetone, was formed as a byproduct.
		I made iodoform in a way, which is somewhat less wasteful on (expensive) iodine and no elemental iodine is needed.

		So, he packed each of the holes with Iodoform gauze and told me to change it daily for a week.
		The problem with iodine is that it kills all cells, so it kills bacteria but it also kills the newly forming cells in the wound.
		The following website says that Iodoform gauze may cause tissue destruction and should be used for less than 5 days.

		Müntz stirs up a weighed quantity of the material to be analyzed in a certain proportion of water, distills it in the smaller of the two apparatus, and detects the alcohol by means of the same operation as before.
		The formation of iodoform by precipitation under the action of iodine and carbonate of soda is a very sensitive test for alcohol.
		Müntz has not been contented to merely submit the iodoform precipitates obtained by him to microscopical examination, but has preserved the aspect of his preparations by means of micro-photography.

		Histologically demonstrated liver damage in the laboratory animals was comparatively mild, but the marked decline in their bromosulphophthalein (BSP) clearance rates indicated severe depletion of liver functional capacity.

		This page looks at how the triiodomethane (iodoform) reaction can be used to identify the presence of a CH CO group in aldehydes and ketones.
		The reason that sodium chlorate(I) is alkaline is that it reacts reversibly with water to form the weak acid chloric(I) acid together with hydroxide ions.
		and the rest of the molecule is broken to produce triiodomethane (iodoform) and the salt of an acid.

		A positive test will result in the brown color of the reagent disappearing and the yellow iodoform solid precipitating out of solution.
		If the substance to be tested is insoluble in water, dissolve it in 2 mL of 1,2-dimethoxyethane, proceed as above, and at the end dilute with 10 mL of water.
		Formation of solid iodoform (yellow) is a positive test.

	IODOFORM (TRIIODOMETHANE)
		Iodine is required in small amounts in human body for the function of the thyroid gland.
		Iodine forms many important compounds of iodine such as iodine(V)oxide, potassium iodide, iodine trichloride and iodoform of an Iodine containing organic compound.
		Iodoform is a simple structural compound; greenish yellow hexagonal solid with a strong, penetrating odor; containing about 96 per cent of iodine; melting point 119 C; soluble in chloroform and ether and somewhat in alcohol and water: used as a topical anti-infective, applied to the skin.

		These authors also report that, on a molar basis, iodoform has an acute toxicity in mice similar to that of methyl iodide; this conclusion is based on parameters of lethality, barbiturate sleeping time, and bromsulphalein (BSP) retention time.
		1-1117) of iodoform indicates that the substance is not carcinogenic nor of high systemic toxicity, although histopathological examination of laboratory animals in this bioassay was judged by NCI to be inadequate.
		OSHA concludes that this limit will protect workers from the significant risks of irritation and hepatotoxicity, both material impairments of health that are associated with exposure to iodoform.
