osazone Chem.|ˈəʊsəzəʊn|
[f. the suffix -osazone, ad. G. -osazon (E. Fischer 1884, in Ber. d. Deut. Chem. Ges. XVII. 580): see -ose2, azo-, and -one.]
Any of the yellow crystalline solids whose molecules contain two adjacent hydrazone groups, which are obtained by treating compounds containing the groups {b1}CO·CHOH{b1} or {b1}CO·CO{b1} with phenylhydrazine and are used for characterizing sugars.
1888Jrnl. Chem. Soc. LIV. 1267 The osazones of all saccharoses dissolve in cold, fuming hydrochloric acid with a dark-red coloration. 1938M. L. Wolfrom in H. Gilman Org. Chem. II. xvi. 1404 The three fundamental procedures used by Fischer..in his great feat of elucidating the configuration of the sugars were osazone formation, oxidation to meso acids.., and the methods for building up or degrading the members of the sugar series. 1972J. W. Suttie Introd. Biochem. iii. 28 Sugars which differ in configuration only at carbons 1 or 2, such as glucose, mannose, and fructose, will give the same osazone. |
