溶解度：Practically insoluble in water, freely soluble in ethanol (96 per cent), soluble in trimethylpentane and in fatty oils.It is sensitive to air, heat and light. Solutions in solvents without an antioxidant are unstable and are to be used immediately.A reversible isomerisation to pre-cholecalciferol takes place in solution, depending on temperature and time. The activity is due to both compounds.
