uramiln.

Brit.

/ˈjʊərəmɪl/,

/ˈjɔːrəmɪl/, U.S.

/ˈjʊrəm(ə)l/

Forms: 1800s uramile, 1800s– uramil.

Origin: A borrowing from German. Etymon: German Uramil.

Etymology: < German Uramil (F. Wöhler & J. Liebig 1838, in Ann. der Pharm. 26 269) < ur- (in Urea urea n.) + am- (in Ammoniak ammoniac n.) + -il (perhaps a variant of -yl -yl suffix). Compare French uramile (1838).

Chemistry.

A crystalline compound obtained by hydrolysing alloxantin, murexide, and some related compounds. Also called dialuramide, murexan.Systematic name: 5-aminobarbituric acid; C₄H₅N₃O₃.

1839 J. W. Webster Man. Chem. (ed. 3) 429 The solution of uramil in ammonia and caustic potassa acquires a purple colour by exposure to the air, and deposits green acicular crystals.

1840 R. Hare Brief Expos. Sci. Mech. Electr. 489 Uramile crystallizes in thin and hard tufts; or presents itself in the form of a brilliant white powder.

1869 R. Bridges Fownes's Man. Elem. Chem. (ed. 10) 730 Uramile, heated with aqueous solution of potassium cyanate, is converted into pseudo-uric acid, C₅N₄H₆O₄.

1924 J. B. Cohen Pract. Org. Chem. (ed. 3) 470 Alloxan and ammonium sulphite form thionuric acid, which is decomposed by hydrochloric or sulphuric acid into uramil.

1968 I. L. Finar Org. Chem. (ed. 4) II. xvi. 704 Purpuric acid slowly hydrolyses in solution to form alloxan and uramil.

2008 Reactive & Functional Polymers 68 254/2 Uramil contains three main positions available for halogenation which gave the opportunity to prepare multi-halogen biocidal polymers.
