Description

Dark red odorless solid; Hygroscopic; [Merck Index] Dark red powder; [Sigma-Aldrich MSDS]

Sources/Uses

Produced by bacteria, cobalamins (hydroxocobalamin and cyanocobalamin) are analogs of vitamin B12 that differ only in the beta-ligand of the cobalt; Found in fish, meat, liver, and dairy products, but not in plants; Also occur naturally in soil, water, activated sewage sludge, and manure; Used as a vitamin (hematopoietic); [Merck Index] Used as a nutritional supplement and stabilizer or thickener for foods; [FDA] Permitted for use as an inert ingredient in non-food pesticide products; [EPA] Used to perform Schilling's test (pernicious anemia or other malabsorption disorders), as a medicine, nutrient, and animal feed supplement; [HSDB] Hydroxocabalamin is used to treat cyanide poisoning. [Olson, p. 563]

Comments

Patients treated with IV hydroxocobalamin have red urine and erythema; [Olson, p. 563] May cause irritation; [Sigma-Aldrich MSDS]
