Umbelliferone, also known as 7-hydroxycoumarin, hydrangine, skimmetine, and beta-umbelliferone, is a natural product of the coumarin family.

It absorbs ultraviolet light strongly at several wavelengths. There are some indications that this chemical is antimutagenic,^[1] it is used in sunscreens.^[2] Umbelliferone has been reported to have antioxidant properties.^[3]^[4]

It is a yellowish-white crystalline solid that has a slight solubility in hot water, but high solubility in ethanol.
