Inositol or cyclohexane-1,2,3,4,5,6-hexol is a chemical compound with formula C6H12O6, a sugar alcohol. It exists in nine possible stereoisomers, of which the most prominent form, widely occurring in nature, is cis-1,2,3,5-trans-4,6-cyclohexanehexol, or myo-inositol (former names meso-inositol or i-inositol). Its taste has been assayed at half the sweetness of table sugar (sucrose).
Contents
Properties
Chemical
Inositol can be nitrated to give inositol hexanitrate using a nitrating mixture.
Oxidation with nitric acid gives rhodizonic acid.
Inositol may be recrystallized from water or 50% ethanol/water, from which a dihydrate results. It may be dehydrated to a non-hygroscopic anhydrous form.[4]
Physical
Inositol is a crystalline solid, soluble in water.
Availability
Inositol is available in many health food stores. It is sold as a food supplement, sometimes mixed with taurine.
It can also be bought online cheaply.
Preparation
Inositol is best bought than made.
Projects
- Make rhodizonic acid and potassium rhodizonate
- Make inositol hexanitrate
Handling
Safety
Inositol has low toxicity and it's 100% edible. Lab-grade inositol however, isn't.
Storage
Inositol should be kept in closed bottles, plastic bottles are sufficient.
Disposal
Inositol doesn't require special disposal. Discard it as you wish.
