Talk:Catechol

message: Probably uncontroversial, but why not move this article to catechol?  Please leave a note if you have concerns.--Smokefoot (talk) 17:21, 8 February 2009 (UTC)
replies: text: You mean simply rename this article and run the redirect the other way, from pyrocatechol to catechol? Sure. Since 1,2 dihydroxybenzene is better known now as catechol than its historical name, and since a search on either will still recover the needed info, let's switch.

thread_title: Proposed move to catechol

message: Catechol was cytotoxic to neuroblastoma N2a cells in vitro. The minimal cytotoxic concentration after 72 h was 20 micromol/l. The concentration that killed 50 % of cells (EC50) was 38 micromol/l after 72 h. Catechol induced reduced glutathione (GSH) depletion after 24 h, prior to cell death by apoptosis.[1]  —Preceding unsigned comment added by 200.128.60.24 (talk) 21:54, 3 August 2009 (UTC)
thread_title:  Cytotoxicity 

message: The opening phrase states that Catechol has a semi-empirical formula C6H4(OH)2. What exactly does this mean? This is also particularly confusing as this is its molecular formula. I have not come across this term in my degree. Is it in reference to hydrogen bonding networks this molecule participates in the solid state? I think this should be changed to just simply molecular formula, especially as in solution where most chemical reactions occur I would expect it to behave as discreet single units of 1,2-dihydroxybenzene (depending on solvent). Any comments/ideas?

thread_title:  Semi-empirical formula??? 

message: I've been trying to discover the origin of the name "catechol".
When Hugo Reinsch discovered catechol in 1839, he called it Brenz-Katechusäure (burned catechu acid).Hugo Reinsch (1839) "Einige Bemerkungen über Catechu" (Some observations about catechu), Repertorium für die Pharmacie, 68 :  49-58.  Catechol is named Brenz-Katechusäure on p. 58. 
In 1841, both Wackenroder and Zwenger independently rediscovered catechol.  Wackenroder called it Brenzcatechusäure,H. Wackenroder (1841) "Eigenschaften der Catechusäure" (Properties of catechu acid), Annalen der Chemie und Pharmacie, 37 : 306-320.  He names catechol on p. 309. whereas Zwenger called it Brenzcatechin.Constantin Zwenger (1841) "Ueber Catechin" (On catechin), Annalen der Chemie und Pharmacie, 37 : 320-336.  He names catechol on p. 327.
In 1841, the English-language science journal, Philosophical Magazine, reported on Wackenroder and Zwenger's work, and rendered their names for catechol as pyrocatechin.(Anon.) (1841) "On catechin (catechinic acid) and pyrocatechin (pyrocatechinic acid)", Philosophical Magazine, 19 : 194-195.  
Thereafter, catechol had many names, each name depending on the substance from which the catechol had been obtained.  Some years were required before chemists realized that all of these substances were the same compound.  — Preceding unsigned comment added by VexorAbVikipædia (talk • contribs) 14:56, 18 April 2015 (UTC)
replies: text: Interesting insights.  Such specialized historical research would be ideal for J. Chem. Ed.  It is probably not, IMHO, suitable for Wikipedia per WP:NOTJOURNAL. --Smokefoot (talk) 14:28, 18 April 2015 (UTC)
replies: text: Yes, I would agree that this subject is rather recondite.  Typically, "John Smith" discovers compound XYZ and names it.  However, in the case of catechol, the naming process was more convoluted:  from pyrocatechin to pyrocatechol to catechol.  Furthermore, the compound's names were (apparently) coined by anonymous editors.  So in the article, I included only as many details as I thought necessary to explain the changes of name.VexorAbVikipædia (talk) 21:06, 18 April 2015 (UTC)
replies: text:  I, on the other hand, am in favor of cramming as much information as possible into Wikipedia, per WP:NOTPAPER. Such stuff is easy to skip over for those not interested, and quite invaluable as a time-saver for those who are. The separate question of what counts as WP:OR is a difficult and unresolved one, and IMHO, unresolvable. Generally a historical review of a subject drawn from many sources cannot avoid WP:SYNTH, nor should it, as the only type of WP:SYNTH that is really off limits is that which argues novelly toward some POV that is shockingly new and worthy of publication as some really amazing new historical synthesis of events that will interest scholars and overturn historical dogma (NOT a simple non-controversial chronological ordering as you give above). The kind of synthesis that results in ordinary WP:NPOV is still a kind of synthesis (a balanced kind) and if you read the policy on WP:SYNTH you will see that Wales and the early Wikipedists recognized this. However, later it became fashionable to deny this point, because it made heads explode to try to differentiate one type of SYNTH from the other, so it was just easier for some to boldly deny that any WP:SYNTH ever properly occurs, and pass on. Of course, that's nonsense. Wikipedia progresses in the WP:SYNTH department by the simple expedient of WP:IAR. In this case, one has no choice. Writing encyclopedia articles as a distillation from sources that contain very much more information IS a synthetic activity, if the word means anything at all. A non-judgmental computer with no sense of historical or pedagogical taste, could not possible do it. SBHarris 22:06, 18 April 2015 (UTC)
