What it is Filled
Nicodicodine is a semisynthetic opioid derived from dihydrocodeine by esterifying its 6-hydroxyl group with nicotinic acid.
In scope
- Molecular connectivity, stereochemistry, synonyms and external identifiers
- Free-base identity and relationships to documented salts or solvates
- Analytical identification, assay basis and related-substance impurities
- Physical properties and stability under recorded conditions
- Evidence for biological activity, exposure hazards and applicable controls
Out of scope
- Finished medicines, formulations, brands and packaging
- Patient diagnosis, prescribing and dosing decisions
- Manufacturing processes and synthesis instructions
- Independent models of dihydrocodeine, nicocodine and nicotinic acid
- Organization-wide licensing and laboratory management
Why it exists Filled
Enable an agent to recognise nicodicodine, assess the identity and condition of a sample, and determine which handling or use decisions have adequate evidence and authorization.
Distinguishing features Filled
- Require the dihydrocodeine scaffold with a nicotinic-acid ester at the 6-position; nicodicodine is not merely a mixture of dihydrocodeine and nicotinic acid. [NIST nicodicodine](https://webbook.nist.gov/cgi/cbook.cgi?ID=C808242&Units=SI)
- Check the 7,8 saturation state: nicocodine is the corresponding codeine ester and has formula C24H24N2O4. [NIST nicocodine](https://webbook.nist.gov/cgi/cbook.cgi?ID=C3688662&Units=SI)
- Cross-check the neutral substance against formula C24H26N2O4 and CAS 808-24-2. [NIST nicodicodine](https://webbook.nist.gov/cgi/cbook.cgi?ID=C808242&Units=SI)
- Require stereochemical evidence before treating a connectivity-only database match as confirmation of the intended substance.
- Distinguish covalent nicotinate ester identity from any counterion associated with a salt sample.
