Prototype of the family of naturally occurring cobalt coordination compounds knows as corrinoids. Analogs of vitamin B12 which differ only in the β-ligand of the cobalt are termed cobalamins. Synthesized almost exclusively by bacteria. Dietary sources include fish, meat, liver, and dairy products; plants have little or no cobalamins. Converted by the body into its bioactive forms, methylcobalamin and cobamamide, which serve as enzyme cofactors. Severe deficiency may result in megaloblastic anemia and/or neurological impairment.||Synonyms:|5,6-Dimethyl-1-(3-O-phosphono-α-D-ribofuranosyl)-1H-benzimidazole Monoester Cobinamide Cyanide Inner Salt; 5,6-Dimethylbenzimidazolyl Cyanocobamide; 5,6-Dimethylbenzimidazolyl-Co-cyanocobamide; Anacobin; Antipernicin; Apikobal; B-Twelve; B-Twelve Ora; Bedodeka; Bedoz; Behepan; Berubi; Berubigen; Dobetin; Docemine; Docibin; Poyamin; Rebramin; Redamina; Vitarubin; Vitral||CAS No:|68-19-9||Molecular Formula:|C63H88CoN14O14P||Molecular Weight:|1355.38||Purity:|≥97%||Appearance:|Dark red crystalline powder||Identification:|Conforms to USP reference||Loss on Drying:|≤10%||Residual Solvents (Acetone):|≤0.5%||Psuedo Cyanocobalamin:|Conforms to USP||Total Plate Count:|≤1000cfu/g ||Yeast and Mold:|≤100cfu/g ||E. coli:|Negative||Meets or exceeds USP specifications
