A white or almost white, crystalline powder, Practically insoluble in water, freely soluble in acetone and in methylene chloride, sparingly soluble in alcohol, The principal spot in the chromatogram obtained with the test solution should be similar in position, colour in daylight, fluorescence in ultraviolet light at 365 nm and size to the principal spot in the chromatogram obtained with reference solution (a). The test should not valid unless the chromatogram obtained with reference solution (b) should show two clearly separated spots.

Storage: Store in an airtight container , protected from light., Freely soluble in water, slightly soluble in alcohol, practically insoluble in methylene chloride, The Infra red absorption spectrum should concordant with the spectrum obtained from std of Betamethasone sodium phosphate or with the Reference Infra red spectrum graph.

A white or almost white powder, Very slightly soluble in water, sparingly soluble in methanol, slightly soluble in alcohol, The Infra red absorption spectrum should concordant with the spectrum obtained from Miconazole nitrate working Standard or reference IR spectrum graph.

Storage: Store in an airtight container, protected from light, A white or almost white powder; very hygroscopic. It shows polymorphism, The principal spot in the chromatogram obtained with the test solution should be similar, in position, colour in daylight, fluorescence in UV light at 365 nm and size to the principal spot in the chromatogram obtained with reference solution (a).The test should not valid unless the chromatogram obtained with reference solution (b) should show two spots which may, however, not be completely separated.

White or almost white, crystalline powder, Practically insoluble in water, freely soluble in ethanol (96 percent), soluble in acetone. It should practically insoluble in dilute hydrochloric acid.

White, crystalline powder, Practically insoluble in water, soluble in acetone and in methanol. Solutions may be opalescent, The chromatogram obtained with test solution should show 2 spots, one of which should correspond in position to the principal spot in the chromatogram obtained with reference solution (a) and the other to the principal spot in the chromatogram obtained with reference solution (b).
