What it is Filled
Kaempferide is a naturally occurring O-methylated flavonol corresponding to kaempferol with its 4′-hydroxy group converted to a methoxy group.
In scope
- Kaempferide molecular identity and distinction from related flavonoids
- Sample purity, impurities, residual solvents and water content
- Analytical identification and quantitative determination
- Physical form, dissolution, stability and storage conditions
- Source provenance and sample-specific handling or use constraints
Out of scope
- Complete models of kaempferol or other methylated flavonoids
- Botanical species and extracts containing kaempferide
- Manufacturing and extraction processes as independently managed systems
- Finished supplements, medicines and other formulations
- Clinical treatment protocols and organism-level disease models
Why it exists Filled
Enable an agent to identify kaempferide, assess the quality and condition of a particular sample, and determine whether evidence supports its intended handling or use.
Distinguishing features Filled
- Require the 4'-O-methyl derivative of kaempferol, with hydroxyl groups at positions 3, 5 and 7; this substitution pattern defines kaempferide. See [ChEBI CHEBI:6099](https://www.ebi.ac.uk/chebi/CHEBI%3A6099).
- Check the neutral formula C16H12O6 and molecular weight 300.26 g/mol against the proposed structure; formula agreement alone cannot resolve positional isomers. See [PubChem CID 5281666](https://pubchem.ncbi.nlm.nih.gov/compound/5281666).
- Require evidence locating methylation on the 4'-oxygen, rather than accepting an unspecified methylkaempferol name or mass match.
- Distinguish the free aglycone from glycosides, charged species and mixtures that merely contain kaempferide.
- Cross-check CAS 491-54-3 and PubChem CID 5281666 against the structure rather than relying on a supplier label alone. See [PubChem identity record](https://pubchem.ncbi.nlm.nih.gov/compound/5281666).
