Talk:Luminol

message: I thought the synthesis used 5-nitro, not 3-nitro. Not sure enough to change it though.  — Preceding unsigned comment added by 140.180.187.50 (talk) 15:49, 10 April 2012 (UTC)
thread_title:  3-nitrophthalhydrazide or 5-nitrophthalhydrazide? 

message: looking at the structure on the page, it looks like there are only 2 oxygen atoms, yet the molecular formula listed has 3 oxygens listed -O3-
I wanted to post this here for the original writer of the article without changing it myself in the case that I had missed something.
Please and thanks for looking into this!  —Preceding unsigned comment added by 99.240.111.89 (talk) 03:51, 6 October 2008 (UTC)
replies: text: As far as I can see it looks like this has been fixed. I can't see O3 mentioned anywhere in the article and the content seems to be coherent with regards to the chemical formulas mentioned. ~Fenrisulfr (talk · work)</font> 21:15, 29 April 2009 (UTC)
thread_title:  Chemical compound components 

message: When was Luminol first discovered, how was it first discovered, and who synthesized it first. If this article is to be comprehensive, that should definitely be in there.  — Preceding unsigned comment added by 76.217.12.210 (talk) 02:55, 2 August 2012 (UTC)
thread_title:  History 

message: The "Technical Note" reference listed in in the links includes a thorough testing of standard aqueous luminol vs. a commercial preparation, and has an extensive list of the other substances that produced false positives when using luminol to locate blood stains.  This could be used to improve the flagged sentences, but it is too long to be included entire; I am not certain what appropriate use would be.  Nightsmaiden (talk) 07:57, 29 July 2009 (UTC)

thread_title:  Medical use 

message: The diagram for the mechanism of luminol (excited triplet state) is incorrect as there is an extra double bond connected to the carbon. The correct mechanism is the same but with carbon having four bonds instead of five. source: http://pubs.acs.org/doi/abs/10.1021/ja01059a051  — Preceding unsigned comment added by 129.171.233.72 (talk) 01:47, 19 April 2013 (UTC)

message: What is meant by But 3-nitrophthalhydrazide itself has the glow.? That it has a glow in addition to luminol? Or that it is in fact what glows? That makes no sense to me since it is involved in the synthesis not the luminescence. Pariah24 (talk) 02:16, 21 May 2020 (UTC)
