B-12

B-12 (Cyanocobalamin, CAS 68-19-9) is the most widely studied synthetic form of vitamin B12, supplied in lyophilised form for laboratory and analytical research use only.

Research background

Cyanocobalamin is characterised in the literature as a stable precursor that is converted in biological systems into the active coenzyme forms methylcobalamin and adenosylcobalamin. These coenzymes act as cofactors for methionine synthase and methylmalonyl-CoA mutase, linking B12 to one-carbon metabolism, DNA methylation, myelin maintenance and red blood cell formation. Because of its stability, cyanocobalamin is commonly used as a reference form in cellular metabolism models and in comparative studies against methylcobalamin and other cobalamin forms.

Testing and verification

Every batch is independently analysed by a third-party laboratory using HPLC-MS to confirm identity, quantity and purity. Each lot is assigned a unique batch identifier and published with its corresponding Certificate of Analysis on our Lab Results page, so the exact paperwork for the batch you receive can be reviewed before a vial is ever opened.
