[Chemical Properties]

White crystals, become pink on exposure to air; colorless aqueous solution which imparts pink color to skin. Soluble in water and alcohol.
[Uses]

Biochemical research, cosmetics, organic synthesis.
[Definition]

ChEBI: A member of the class of pyrimidones, the structure of which is that of perhydropyrimidine substituted at C-2, -4, -5 and -6 by oxo groups.
[Purification Methods]

Crystallisation from water gives the tetrahydrate. Anhydrous crystals are obtained by crystallisation from acetone, glacial acetic acid or by sublimation in vacuo. [See below and Beilstein 24 H 500, 24 I 428, 24 II 301, 24 III/IV 2137.]
