Explain about Cyanocobalamin
Cyanocobalamin occurs as dark red crystals or as a crystalline hygroscopic powder of the same colour without odour and taste. Upon standing in the air, the anhydrous substance absorbs up to 12% water. Cyanocobalamin is soluble in water and 95% ethanol, but almost insoluble in ether, chloroform and petroleum ether. In the presence of alkalis and reactive alkaline compounds, reducing and oxidizing agents, aqueous solutions of cyanocobalamin are not stable. Cyanocobalamin substance and solution gradually decompose with discolouration by the action of day light and UV light. The activity of cyanocobalamin solutions may also be considerably affected by microbial growth. Cyanocobalamin should be kept in air tight containers protected against light and moisture in a cool place. To be protected against mold growth during storage.
