Untitled[edit]

The difference between Quinoline and E104 needs to be properly defined; these compounds are completely different. When I've had a bit of practice here I'll make the adjustments myself.

EDIT: Sorted out the mess a bit. Now... when E104 is searched can it redirect to the Quinoline yellow article rather than this one?

Interesting. Benzo[b]pyridine, quinoline just a few years ago was DEFINITIVELY linked to causing lung cancer as a carcinogenic component of cigarette smoke. No sign of anything like that now. THANK YOU FOR SMOKING!! 70.106.60.44 03:06, 8 January 2007 (UTC)


Need help[edit]

Wow, there's a set of articles here that really needs some work. Looking through several different articles relating to Quinoline (including tryptophan, the biochemical precursor) I failed to find any information regarding several important subject areas with concern to quinoline. Namely the role of quinolinic acid in neurotransmission or as an excitoneurotoxin. I also found no information regarding the role of increased levels of quinolinates in the brains of AIDS patients and the resulting dementia. In fact there's only a passing mention of dementia (no causes explained) in the AIDS article. There's a lot of information missing here. I would appreciate any and all help. --Jmcclare (talk) 18:37, 7 February 2008 (UTC)

Quinoline is also used in the poisoned Lindlar's catalyst for oxidizing alkynes to alkenes.63.231.142.203 (talk) 03:36, 27 January 2009 (UTC)

Uses in colognes?[edit]

I saw on the ifraorg (international fragrance organization) that quinoline was prohibitted in fragrances now? Was it in there before? Why was it prohibited? Is there a problem caused with inhalation or application to skin? I'm no chemistry whiz, but if more folks look for info on this matter I think it might be helpful. Right now if you go to amazon you'll see that some perfumes are prohibted for shipment to catalina island because of some of these chemicals. The ifraorg document is here: http://www.ifraorg.org/files/documentspublished/1/en-us/PR/22361_PR_2010_07_12_IFRA_Issues_latest_update_to_global_fragrance_regulations.pdf —Preceding unsigned comment added by 72.84.235.168 (talk) 01:44, 24 November 2010 (UTC)

Manufacturers[edit]

I don't think that it is used much at all any longer and that the applications listed are probably woefully out of date (i.e., should be was instead of is). Can anyone identify a manufacturer other than an Aldrich or equivalent? The pricing shown in Aldrich would indicate that it is not readily available. JSR (talk) 21:46, 13 January 2017 (UTC)

Well the article says only 4 tons are made/produced per year. Seems reasonable, but such a miniscule amount would be difficult to investigate. I doubt if Aldrich makes it, they mainly resell other people's products is my info. In the US, probably a lot comes from coal tar, e.g. the old Reilly plant in Indianapolis. --Smokefoot (talk) 22:24, 13 January 2017 (UTC)
The author of that article worked for Rutgers, which is like Reilly's. I have sold a lot of stuff to Aldrich and I can always tell the stuff they get from bulk suppliers versus stuff that is made for them by the price. I will get more quinoline is produced in organic lab than commercially. JSR (talk) 23:36, 13 January 2017 (UTC)
