5,7-Dihydroxy-2-(4-hydroxyphenyl)-8-(3-methyl-2-buten-1-yl)-4H-chromen-4-one(CAS: 72357-31-4)

The compound is a crystalline solid with a molecular weight of approximately 343.33 g/mol. It is slightly soluble in water and more soluble in organic solvents like ethanol and acetone. Chemically, it is moderately reactive, particularly towards nucleophiles and electrophiles. It exhibits good stability under normal storage conditions but requires handling under an inert atmosphere to prevent degradation.

This compound can be synthesized via a condensation reaction between a substituted chromone and an aldehyde, followed by reduction and ring closure. Common catalysts include palladium on carbon, and the reaction typically yields a mixture of diastereomers. Optimal conditions include use of a mild reducing agent and appropriate solvent to ensure high selectivity and yield.

This compound finds application in the pharmaceutical industry for its potential as a drug precursor, in the polymer industry for its use as a monomer, and in the sensor industry due to its chromogenic properties. It is also explored in semiconductor research for its photochemical and electronic properties.

Handle the compound in a well-ventilated area or fume hood due to its potential to produce volatile compounds. Wear appropriate personal protective equipment (PPE), including gloves, goggles, and a lab coat. Store in a cool, dry place away from direct sunlight. In case of spill, immediately clean up using appropriate absorbent materials and refer to the safety data sheet (SDS) for further guidance.
