This page holds two records that were compiled separately. The research figures below come from the public registries named under each one, each read on the date printed beside it. The supplier prices at the foot were read on the suppliers own sites on the dates in that table. Nothing here was produced by this publication measuring anything.
Identity and computed properties
PubChem holds this compound as CID 166596686, molecular formula C63H88CoN14O14P, average mass 1355.4 daltons and monoisotopic mass 1354.5674 daltons, read on 2026-09-19. Those masses are computed from the deposited structure and were not measured on any material, so they are the expected value an identity check compares against rather than evidence about any vial.
The title that record carries for the CID is Cyanocobalamin. Its synonym list runs to 55 entries.
Receptors the literature describes
No published paper this search reached describes a receptor this compound acts at.
The registered trial record
An intervention search of clinicaltrials.gov for the term cyanocobalamin, read on 2026-09-19, returned 752 registered studies: 7 early phase 1, 41 phase 1, 123 phase 2, 99 phase 3, 59 phase 4 and 464 recorded with no phase.
Harvard School of Public Health (HSPH) is lead sponsor on 15 of the 752 records. The remaining 737 name 512 other organizations.
On the date read, the statuses those records carried were 447 completed, 146 unknown and 59 recruiting, among others.
The earliest record the search returns is NCT00004495, first submitted 1999-10-18. That date is a floor, not an origin: earlier work may sit in the registry under a code number this search term does not match.
Registry counts measure registration, not knowledge.
The publication record
PubMed answered 31,368 records for the term cyanocobalamin on 2026-09-19. Of those, 1,367 carry a clinical-trial publication type, and 19 of those carry Clinical Trial, Phase III. 3,006 carry the publication type Review, which is other people reading the rest.
PubMed counts measure indexing, so work in venues it does not index is invisible to this figure. The term that produced it is printed above so it can be run again.

Adverse events, as published reports recorded them
This block was compiled and no adverse event from a named publication was reached.
Spontaneous report databases are not used on this page. A count of reports carries no denominator, so it cannot be read as a rate and is not printed as one.
Who it is not given to
labelThe cyanocobalamin injection label gives one reason not to use it. Being sensitive to cobalt, or to vitamin B12 itself. Vitamin B12 has a cobalt atom at its centre, which is why cobalt matters here.Cyanocobalamin injection label · read 2026-09-19
Most approved products carrying this ingredient are combination vitamins. The first record this search returned was a prenatal multivitamin whose strongest warning is about omega-3 fatty acids and accidental iron overdose, neither of which has anything to do with vitamin B12. A warning attached to a mixture is not a warning about one ingredient in it.read 2026-09-19
Every row is a price read on that supplier's own site, divided by the milligrams it buys. Cheapest first, which is not a ranking of quality: the columns beside the rate show what this publication could confirm about the evidence behind it. Some supplier links here are referral links, marked where they appear, which pay Terminus Research when a reader buys. The same terms are open to every supplier in the ledger, apart from the one exception the referral policy page names, participation changes no score, rank, caution, or coverage decision, and a link is not an endorsement.
