purpuric acid
From Wiktionary, the free dictionary
Etymology
Named by Dr W. H. Wollaston "from its remarkable property of forming compounds with most bases of a red or purple colour" (as reported by William Prout in Philosophical Transactions of the Royal Society of London, Vol. 108 in 1818, pages 420-428).
Noun
- (chemistry) C8H5N5O6, a nitrogenous acid that yields alloxan and uramil when hydrolysed, known for its purple salts.
Usage notes
At first, the name was applied to a "substance discovered by Prout, which had neither a purple colour, nor possessed acid properties, but it was so named, because it was extracted, by means of an acid, from purpurate of ammonia", and its composition was thought to be H8C16O10N10 (as reported in the London and Edinburgh Philosophical Magazine and Journal of Science, volume XV, July—December 1839, Daid Brewster, Richard Taylor, Richard Phillips, eds, page 491).
