Comprehensive structural overview

4-DMA-7,8-DHF is a synthetic flavone derivative belonging to the broader class of polyphenolic chromenone compounds. The molecular structure contains a flavone backbone consisting of a benzopyran ring system fused with a phenyl substituent.

The compound includes hydroxyl substituents at the 7 and 8 positions of the chromenone ring and a dimethylamino group on the phenyl ring. This substitution pattern contributes to defined physicochemical characteristics including polarity, hydrogen bonding potential and spectroscopic behaviour.

Flavone class context

Flavone derivatives are characterised by a 2-phenylchromen-4-one core structure. Structural diversity within this class arises from the position and nature of substituents on the aromatic rings and chromenone backbone.

Hydroxylated flavones commonly exhibit defined UV absorption patterns due to conjugated aromatic systems and electron delocalisation across the chromenone scaffold.

Functional group analysis

4-DMA-7,8-DHF contains several functional groups relevant to analytical chemistry:

• Phenolic hydroxyl groups
• Aromatic ring systems
• Ketone (chromenone carbonyl)
• Tertiary amine (dimethylamino substituent)

The phenolic hydroxyl groups participate in hydrogen bonding interactions, while the conjugated aromatic system contributes characteristic absorption bands in spectroscopic analysis.

Molecular architecture and electronic distribution

The molecular formula C₁₇H₁₅NO₄ reflects an aromatic polyphenolic structure combined with a tertiary amine substituent. Conjugation across the chromenone ring system enables π-electron delocalisation that influences UV-visible absorption behaviour.

This electron distribution contributes to defined chromatographic retention behaviour and spectroscopic identification in laboratory workflows.

Spectroscopic characteristics

NMR Spectroscopy: Proton NMR spectra typically display aromatic proton resonances associated with the phenyl and chromenone rings, along with signals corresponding to the dimethylamino substituent.

Infrared Spectroscopy: The chromenone carbonyl produces a characteristic strong absorption band, while phenolic O–H stretching bands are typically observed in the higher wavenumber region.

UV-Visible Spectroscopy: The extended aromatic conjugation system produces characteristic π→π* transitions detectable in UV analytical systems.

Chromatographic behaviour

4-DMA-7,8-DHF exhibits defined retention characteristics in reversed-phase chromatographic systems. Aromatic ring structures interact with hydrophobic stationary phases while hydroxyl groups contribute additional polarity-dependent interactions.

Mass spectrometric analysis

Mass spectrometry confirms a molecular weight of 297.31 g/mol. Fragmentation patterns commonly involve cleavage within the aromatic substituent and chromenone backbone, supporting structural verification during analytical workflows.

Solid-state characteristics

4-DMA-7,8-DHF is typically encountered as a yellow to light orange crystalline powder. Polyphenolic flavone derivatives commonly display stable solid-state behaviour when stored under controlled laboratory conditions.
