xanthicadj.

Brit.

/ˈzanθɪk/, U.S.

/ˈzænθɪk/

Etymology: < French xanthique, < Greek ξανθός yellow: see -ic suffix.

1. Chemistry. Epithet of certain compounds which produce substances of a yellow colour, or of bodies connected with these.

a. xanthic oxide, the original name of xanthine n.; so xanthic calculus, a urinary calculus containing xanthine.

1817 A. Marcet Ess. Chem. Hist. Calculous Disorders iv. 99 If the potash be added to the pure xanthic substance,..no change of colour takes place. The residue of the solution of xanthic oxyd in water produces the yellow substance, when treated with nitric acid.

1817 A. Marcet Ess. Chem. Hist. Calculous Disorders iv. 101 Xanthic oxyd.

1817 A. Marcet Ess. Chem. Hist. Calculous Disorders iv. 102 In burning, it emitted an animal smell, which did not at all resemble that of the lithic, cystic, or xanthic calculus.

1857 W. A. Miller Elements Chem. III. 642 Xanthic or Uric Oxide (C₁₀H₄N₄O₄) was discovered by Dr. Marcet as the principal constituent of a very rare variety of urinary calculus.

1876 T. Bryant Pract. Surg. (ed. 2) II. xxii. 81 Calculi of uric acid and the urates, with their modifications, the oxalates,..xanthic and cystic oxide.

b. xanthic acid, a complex acid containing sulphur and carbon, also called sulphocarbethylic or ethyldisulphocarbonic acid (C₃H₆OS₂), many of whose salts (xanthates) are yellow. Hence more widely, any acid of the general formula RO·CS·SH or RO·CS·SR′. So xanthic ether, etc.

1885 G. L. Goodale in A. Gray & G. L. Goodale Bot. Text-bk. (ed. 6) II. ii. xiv. 454 The colors of flowers have been variously classified; thus de Candolle divides them into a xanthic (yellow) and a cyanic (blue).
