Applications
4-Hydroxycoumarin is involved in annulation reactions, due to the relatively high acidity of the C-H bond at the 3-position: a three-component reaction with isocyanides and dialkyl acetylene dicarboxylates affords annulated 4H-pyrans.

Solubility
Soluble in ethanol and dimethyl formamide. Insoluble in water.

Notes
Store in cool place. Keep container tightly closed in a dry and well-ventilated place. Incompatible with strong oxidizing agents and strong bases.
