Hymecromone (4-methylumbelliferone) is a drug used in bile therapy. It is used as choleretic and antispasmodic drugs and as a standard for the fluorometric determination of enzyme activity.[1]
Hymecromone is a crystalline solid with a melting point of 194–195 °C. It is soluble in methanol and glacial acetic acid.
