Delete there must be millions or billions of chemicals; they are not inherently notable. This unsourced one liner doesn't even tell us the chemical formula (like H2O) or anything to indicate why its notable. Carlossuarez46 (talk) 16:19, 15 May 2009 (UTC)
 * Speedy keep. Nominated only 90 mins after creation and could be considered a work in progress. Appears to have been created in support of Psilocin. 1,900 Ghits which suggest it is also used in metallurgy for etching aluminum alloys. 591 uses in Google Scholar and 540 in Google Books supports notability.

 * Hmm, I'm actually rather dubious. The google hits you mention seem to refer to a different "Keller's reagent" - the one mentioned here seems to be an iron-based solution for use in organic chemistry, while all the Google hits I've looked at seem to refer to a hydrofluoric & nitric acid mixture used in aluminium etching. I reckon I could probably produce a reasonable stub on the metallurgy reagent, but the subject of this article as it stands seems unsourceable at first glance. ~ mazca  t 17:48, 15 May 2009 (UTC)
 * Comment the real problem is this is a sub-stub with zero context in a specialized field. It's not even easy for a non-chemist to assess the article. Drawn Some (talk) 17:50, 15 May 2009 (UTC)

 * Comment. Seems to be a reagent used for testing the results in extracting the active compounds from "magic mushrooms"; at, least, I can find no Google hits in other contexts. (Note that the only other WP mention is in Psilocin.) Whether that makes it a notable solution, I don't know. Deor (talk) 20:14, 15 May 2009 (UTC)
 * Comment. Perhaps a stay of execution pending advice from WikiProject Chemistry? McWomble (talk) 13:28, 16 May 2009 (UTC)
 * Keep per this Google scholar search which finds nearly 600 hits in the scientific literature for this. The article is in severe need of improvement but I don't think that's a good reason for deletion. —David Eppstein (talk) 22:49, 16 May 2009 (UTC)
 * All, or almost all, of those hits refer to the dilute mixture of hydrofluoric, hydrochloric, and nitric acids used for etching metal, mentioned by Mazca above. What we're trying to determine is whether the subject of this article, a different "Keller's reagent" entirely, is notable. Deor (talk) 23:44, 16 May 2009 (UTC)
 * I think both reagents are notable. The alkaloid one has uses beyond psylocibin and has been known under that name for at least 100 years; I've added more references to the article documenting this. —David Eppstein (talk) 06:23, 17 May 2009 (UTC)


 * Keep, per excellent improvements by User:David Eppstein. Now a useful, well-sourced stub covering both uses - nicely done. ~ mazca  t 10:14, 17 May 2009 (UTC)
 * Keep per Mazca. Deor (talk) 16:25, 17 May 2009 (UTC)
 * Keep, the current article is significantly improved over the nominated version. Wronkiew (talk) 04:07, 19 May 2009 (UTC)
 * Keep, well-written, sourced article. I don't see any reason to delete.  Lankiveil (speak to me) 06:08, 21 May 2009 (UTC).
