Talk:Coumarin

Kiehlrp (talk) 04:19, 22 July 2011 (UTC)Inconsistency: in the Dutch and German article it is mentioned that the name Coumarin comes from the Spanish word cumarú, which means Tonkabeantree. In the English article however the name is said to derive from a French word. —Preceding unsigned comment added by 131.211.44.114 (talk) 09:35, 6 September 2007 (UTC)

The calculation of coumarin content in cassis is tediously explicit. —Preceding unsigned comment added by 173.89.173.219 (talk) 21:51, 20 January 2009 (UTC)

" However, the coumarin content of these drinks is said to cause headaches." Since all alcoholic beverages can cause headaches, this assertion deserves further documentation. Kiehlrp (talk) 04:19, 22 July 2011 (UTC)

Synonym

The lymphedema reference calls it (5,6-benzo-alpha pyrone). Rod57 (talk) 13:59, 7 September 2009 (UTC)

Yes, that's an accepted synonym: see ChemSpider. Fvasconcellos (t·c) 20:08, 7 September 2009 (UTC)

Mexican Vanilla

I'm told that Mexican Vanilla, the kind they sell in the liquor stores in the bordertowns, contains coumarin, and is not imported for sale in the US for that reason. Could anyone elaborate on this? The vanilla has a cinnamon aftertaste that tends to disflavor chocolate desserts, but I was liking it in vanilla tapioca. A local ice cream chain sells "mexican vanilla" flavor but their spokesperson said that it's really a large amount of regular vanilla. My information is from the Austin American Statesman, in response to a query I sent their Questions editor. — Preceding unsigned comment added by 66.69.251.117 (talk) 07:26, 26 October 2011 (UTC)

Dimerization

One of the major chemical reaction using coumarin is photodimerization with UV irradiation. A topic about this subject is necessary. Noticelly it is a 2-2 cyclisation using the carbon carbon double bound which doesn't belong to the aromatic group. — Preceding unsigned comment added by Liclic en (talk • contribs) 03:48, 6 January 2012 (UTC)
