Etymology: "Uracils" is simply the plural of "uracil," so this entry concerns the word itself. Uracil was coined in 1885 by the German chemist Robert Behrend, who was trying to make derivatives of uric acid. The name is a blend built from three pieces: "uro-" from uric acid, "ac" from "acetic" (the acid family that Behrend was working with), and the chemical suffix "-ile," a common ending in names of organic compounds. Notably, the name was built from parts of other chemical names rather than describing the molecule's structure directly. Behrend's naming reflected the chemistry he was pursuing at the time, and the result was a label that sounds like a substance but records a laboratory pathway.

Synonyms: uracil bases, pyrimidines
