A chiral furocoumarin.
The furocoumarin 1,2-dihydro-2-(1,2-dihydroxyprop-2-yl)-8H-furo[2,3-h]benzopyran-8-one crystallizes from methanol-water as the monohydrate C(14)H(14)O(5).H(2)O. Both chiral centers have the S configuration. Both OH groups and both H atoms of the water molecule form intermolecular hydrogen bonds with O.O distances in the range 2.7686 (18)-2.8717 (18) A.
