Literature References: In wood of old fustic (Chlorophora tinctoria (L.) Gaud., Moraceae), also called Cuba wood, or yellow Brazil wood. The wood of the Osage orange tree also contains morin and maclurin. Isoln: Perkin, Pate, J. Chem. Soc. 67, 649 (1895); Rolland, Teintex 3, 460 (1938).

Properties: Crystallizes with 1 or 2 mols water. Anhydr needles from abs alcohol, dec 285-290°. One gram dissolves in 4 liters water at 20°, in 1060 ml boiling water. Freely sol in alcohol; slightly sol in ether, acetic acid. Sol in aq alkaline solns with intense yellow color which turns brown on exposure to air. Absorpion spectrum: Grinbaumowna, Marchlewski, Biochem. Z. 290, 261 (1937).
 
Derivative Type: Calico yellow
Properties: Obtained by the action of bisulfite on fustic extract consists mainly of the bisulfite compound of morin, C15H10O7 + NaHSO3, and is used in calico printing. The calico yellow of commerce is a good source of morin for the laboratory. The bisulfite is removed with HCl.
 
Use: As a spot test reagent for Al, Be, Zn, Ga, In, and Sc salts: Feigl, Spot Tests (New York, 1954); Beck, Mikrochim. Acta 2, 287 (1937). As luminescence indicator: Kocsis, Zádor, Z. Anal. Chem. 124, 42-45 (1942). As a textile dye, morin dyes wool mordanted with chromium: olive yellow; mordanted with aluminum: yellow; mordanted with tin: lemon yellow; mordanted with iron: deep olive brown.
