Definition
4'-Hydroxyflavanone is a chemical name that designates a flavanone molecule bearing a single hydroxyl (‑OH) substituent at the 4' position of the B‑ring. No widely recognized encyclopedic entry currently exists for this specific compound.
Overview
Flavanones are a subclass of flavonoids, polyphenolic compounds commonly found in plants. The basic flavanone skeleton consists of a 2‑phenyl‑chroman‑4‑one core. Substitutions on the aromatic rings give rise to numerous derivatives with varying biological activities. A hydroxy group at the 4' position modifies the compound’s polarity and potential reactivity, but detailed information about the physicochemical properties, synthesis, or biological effects of 4'-hydroxyflavanone is not readily available in mainstream reference works.
Etymology / Origin
The name follows standard IUPAC‑style nomenclature for flavonoids:
- “flavanone” identifies the core 2‑phenyl‑chroman‑4‑one structure.
- “4'-hydroxy‑” indicates a hydroxyl substituent attached to carbon 4' of the B‑ring (the phenyl ring attached at position 2 of the chroman system).
The term likely arises in specialized chemical literature describing synthetic intermediates or natural product derivatives, though a definitive source cannot be confirmed.
Characteristics
Because specific experimental data are not compiled in widely accessible encyclopedic sources, the following characteristics are inferred from general flavanone chemistry:
- Molecular Formula: Expected to be C₁₅H₁₂O₂ (flavanone C₁₅H₁₂O₂, plus one additional oxygen for the hydroxy group, yielding C₁₅H₁₂O₃).
- Molecular Weight: Approximately 236 g·mol⁻¹.
- Solubility: Likely limited in water, moderately soluble in organic solvents such as methanol, ethanol, or DMSO, similar to other monohydroxy flavanones.
- Spectroscopic Features: UV‑Vis absorption typical of flavanones (peak around 280 nm) with possible bathochromic shift due to the 4'‑hydroxy group.
- Potential Reactivity: The phenolic hydroxyl may undergo typical reactions such as methylation, sulfation, or glycosylation.
