References of 2-(4-hydroxy-3,5-dimethoxyphenyl)chromenylium-3,5,7-triol
Title: Malvidin Chloride
CAS Registry Number: 643-84-5
CAS Name: 3,5,7-Trihydroxy-2-(4-hydroxy-3,5-dimethoxyphenyl)-1-benzopyrylium chloride
Synonyms: 3,4¢,5,7-tetrahydroxy-3¢,5¢-dimethoxyflavylium chloride; enidin; primulidin; syringidin; 3,4¢,5,7-tetrahydroxy-3¢,5¢-dimethoxy-2-phenylbenzopyrylium chloride
Molecular Formula: C17H15ClO7
Molecular Weight: 366.75
Percent Composition: C 55.67%, H 4.12%, Cl 9.67%, O 30.54%
Literature References: Found as the diglucoside (malvin) in wild malve (Primula viscosa All., Primulaceae) and as the monoglucoside in blue grapes: Willst?tter, Mieg, Ann. 408, 122 (1915); Karrer, Widmer, Helv. Chim. Acta 10, 5 (1927). Structure: Anderson, Nabenhauer, J. Am. Chem. Soc. 48, 2997 (1926). Synthesis: Bradley, Robinson, J. Chem. Soc. 1928, 1541.
Properties: Prisms or rhombic tablets, appearing red by transmitted light with a green luster when dry or with a steel-blue luster when in contact with solvent. Usually obtained as the mono- or dihydrate. The anhydr salt is very hygroscopic. Not melted at 300°. Sol in abs alc, giving a violet-red soln. Sparingly sol in water. Also sol in amyl alc. In methanol the substance is first sol with purple color, then begins to separate as red crystals which are violet by transmitted light.
