ABOUT THE MATERIAL
Identity, scientific context and the details that distinguish this entry.
Vitamin B12 is supplied as cyanocobalamin aqueous solution at 1 mg/mL, with 10 mg in each 10 mL vial.[Sources]
Cyanocobalamin is a cobalt-containing cobalamin with a cyano upper ligand. B12 research connects cobalamin chemistry with one-carbon metabolism and mitochondrial methylmalonyl-CoA processing.
The upper cobalt ligand distinguishes methyl-, adenosyl-, cyano- and hydroxocobalamin. Active cofactor reactions use specific forms, so chemical form and cofactor activity are separate from the catalogue vial amount.
A CLOSER LOOK
Read each finding with its study model and material identity.
The crystal structure examined methylcobalamin-containing domains of bacterial methionine synthase. It showed the corrin cofactor environment and replacement of the free-cofactor cobalt ligand by a protein histidine. This provides a structural view of B12–protein interactions and cofactor chemistry.
NIH describes methylcobalamin and adenosylcobalamin as metabolically active forms. Methionine synthase links B12 to folate-dependent remethylation, while methylmalonyl-CoA mutase links it to mitochondrial carbon metabolism. These are enzyme/cofactor relationships rather than peptide-receptor interactions.

BEFORE YOU ENQUIRE
The concentration is 1 mg/mL and the fill volume is 10 mL, giving 10 mg cyanocobalamin per vial. One box contains 10 vials.
Use the specification and available safety or stability information for the offered lot, form and packaging. Request written conditions before ordering; literature alone does not establish a universal temperature, shelf life or reconstitution procedure.
The displayed value is a catalogue specification. Assess the offered lot against its matching COA and method. Chromatographic purity, component content and biological activity are different measurements; confirm which results are available.
Include the exact SKU, quantity in boxes, destination, desired timing and document requirements. State any label or packaging needs. Pricing, availability, lead time and document scope are confirmed in the quotation.
