Calcipotriol Monohydrate BP
Chemical Name : (5Z,7E,22E,24S)-24-Cyclopropyl-9,10-secochola-
5,7,10(19),22-tetraene-1a,3b,24-triol monohydrate.
Empirical Formula : C27H40O3,H2O
Molecular Weight : 430.6
Chemical Structure :
Description : White or almost white, crystalline powder.
Solubility : Practically insoluble in water, freely soluble in
ethanol (96 per cent), slightly soluble in methylene
chloride.
It is sensitive to light.
A reversible isomerisation to pre-calcipotriol takes
place in solution, depending on temperature and
time. The activity is due to both compounds.
