It appears as an almost white, or white, crystalline powder that is freely soluble in water, chloroform,ethanol and methanol; slightly soluble in acetonitrile and practically soluble in ethe. Dexmedetomidinehas one chiral centre and is therefore optically active. During the synthesis only one (S)-enantiomer is manufactured and used in the manufacture of the finished product. There are two recognisedpolymorphic forms of dexmedetomidine: anhydrous (form A) and monohydrate (form B). Form A is consistently obtained during synthesis and is used in the manufacture of the finished product.
