Comments[edit]

To generate InChI identifiers for molecules, use eg this page

InChI converter

What will be of interest is to see if a Wiki search of these strings retrieves the article correctly. See for example this article.

This would, if it works, allow molecular structure searching (but not sub-structure) in Wikipedia. It is unfortunately, currently only a matter of conjecture how many valid molecules have been deposited into Wikipedia articles. Perhaps 1000 or so? Many more? In theory, a search for the string InChI=1/ would give us an answer, assuming each molecule had an InChI!

Delay in updating the search index[edit]

From the help page, one finds this

For reasons of efficiency and priority, very recent changes are not always immediately taken into account in searchers At the moment, the search engine uses an index that isn't updated at all.

That means I could not test for an InChI.

Other synonyms: mauve aniline, violine[edit]

It seems that mauve aniline and violine were/are other common names for the dye. (Dictionary.com covers lists them as meaning the same thing). However, this 1861 article refers to violine and aniline purple as distinct, I'd guess similar but produced through different means and with somewhat different properties. Not knowing more details of the different meanings, or commonality of usage, I don't want to add something to the article that might be wrong, but thought I'd mention the terms here in case someone else knows or wants to find out more about the terms, to integrate into the article. -Agyle 22:00, 25 September 2007 (UTC)[reply]

InChI[edit]

This should go into a chembox, not the article body--Bfesser (talk) 17:39, 23 December 2007 (UTC)[reply]

Merge with Aniline Purple?[edit]

This article is extremely similar to the page titled, "Aniline Purple." They should be put into one article, with an introduction including something along the lines of, "Mauveine, otherwise known as aniline purple and Perkin's mauvine..." — Preceding unsigned comment added by 66.108.189.139 (talk) 02:18, 2 March 2012 (UTC)[reply]

What the-?[edit]

According to this article, Queen Victoria appeared at the Great Exhibition wearing clothes dyed with Mauveine five years before it was invented... Paul S (talk) 11:15, 19 August 2014 (UTC)[reply]

I have removed this reference as it is clearly incorrect, there were natural (and synthetic) purples before mauveine. In any event, the person adding this reference got the wrong event, it was the wedding of Princess Victoria in 1858 that Queen Victoria wore a purple dress. I have never been able to nail down whether this was dyed with mauveine or French purple (made from orchil) or perhaps murexide (another synthetic purple dye), but it is possible that it was indeed mauveine. I have also removed the reference to Ditto as mauveine was not made commercially after Perkin retired, the purple in Ditto is probably fuchsine (as in methylated spirits) or possibly methyl violet, but certainly not mauveine.

Thanks, I was reluctant to remove the reference myself as I know so little about this subject. Paul S (talk) 17:00, 19 August 2014 (UTC)[reply]
