The Functions of Cyanocobalamin

Cyanocobalamin is also called Cyano-5,6-dimethylbenzimidazole-cobalamin and Vitamin B12.
Water solubility:  Dissolved in water and alcohol, do not dissolve in acetone, chloroform and ether.

Cyanocobalamin is a synthetic (man-made) form of vitamin B12. Naturally occurring vitamin B12 is found in fish, seafood, milk, egg yolk and fermented cheeses. Melting point:  >300°C. Vitamin B12 is essential to the development of healthy blood cells, nerve cells, and proteins in the body and for the normal metabolism of fats and carbohydrates in the body. Lack of vitamin B12 can result in anemia, stomach problems, and nerve damage. Quality Standards: USP30. Cyanocobalamin treats or prevents vitamin B12 deficiency and a resulting type of anemia, called pernicious anemia. Molecular weight :  1355.38. Pernicious anemia occurs in patients who do not have enough vitamin B12 in their diet (e.g., strict vegetarians) or who cannot adequately absorb the vitamin due to a defect or disease of the stomach or intestines.

This compound is found as dark red crystals or an amorphous or crystalline red powder. Cyanocobalamin is very hygroscopic in the anhydrous form, and sparingly soluble in water (1:80). It is stable to autoclaving for short periods at 121 °C. The vitamin B12 coenzymes are very unstable in light.. Cyanocobalamin contains not less than 96.0 percent and not more than 100.5 percent of C63H88CoN14O14P,calculated on the dried basis.
Specification: 96.0%-100.5%Cyanocobalamin
Molecular formula: C63H88CoN14O14P
