Hydroxocobalamin Usage And Synthesis

Uses

Hydroxocobalamin is an intermediate in the synthesis of Nitritocobalamin is a useful synthetic intermediate in the synthesis of Hydroxocobalamin Acetate; a physiological analog of vitamin B12 where the CN group is replaced with OH. Exists in aqueous solution as an equilibrium mixture of the hydroxy isomer and the ionic aqua isomer (aquacobalamin). Precursor of the coenzymes methylcobalamin and cobamamide. Coordination Compound. Vitamin (hematopoietic).

Originator

Alpha-Redisol,MSD,US,1962

Uses

Hydroxocobalamin is an intermediate in the synthesis of Nitritocobalamin(N490240) is a useful synthetic intermediate in the synthesis of Hydroxocobalamin Acetate (H826800); a physiological analog of vitamin B12 where the CN group is replaced with OH. Exists in aqueous solution as an equilibrium mixture of the hydroxy isomer and the ionic aqua isomer (aquacobalamin). Precursor of the coenzymes methylcobalamin and cobamamide. Coordination Compound. Vitamin (hematopoietic).

Definition

A form of vitamin B 12.

Manufacturing Process

A solution containing 26.3 mg of vitamin B12 in 15 ml of water was shaken with 78 mg of platinum oxide catalyst and hydrogen gas under substantially atmospheric pressure at 25°C for 20 hours. Hydrogen was absorbed. During the absorption of hydrogen the color of the solution changed from red to brown. The solution was separated from the catalyst and evaporated to dryness in vacuo. The residue was then dissolved in 1 ml of water and then diluted with about 6 ml of acetone.
After standing for several hours a small amount of precipitate (about 2 to 3 mg) was formed and was then separated from the solution. This solution was diluted with an additional 2 ml of acetone and again allowed to stand for several hours. During this time about 4 to 5 mg of noncrystalline precipitate formed. This solid was separated from the solution and an additional 2 ml of acetone was added to the solution. On standing, vitamin B12a began to crystallize in the form of red needles. After standing for 24 hours, the crystalline material was separated, yield 12 mg. By further dilution of the mother liquor with acetone additional crystalline precipitate formed (from US Patent 2,738,302).

Therapeutic Function

Hematopoietic vitamin

Side effects

Hydroxocobalamin is generally a well-tolerated drug. The adverse effects stem from hypersensitivity reactions to cobalt or other components of the hydroxocobalamin injection. These adverse effects include; exanthema (rash), Itching, fever, nausea, dizziness, rigors, and hot flushes. Anaphylaxis is rare.
