Pantothenic acid (Calcium pantothenate)
Calcium pantothenate is a white, loose, faintly hygroscopic powder without odour and of bitter taste. It is easily soluble in water, glycerin, sparingly soluble in ethanol, acetone and ether; insoluble in chloroform and benzene. A 5% aqueous solution has a pH of 7.2-8.0. Pantothenic acid is stable under neutral conditions but is readily destroyed by heat in alkaline or acidic solution.
