Tiny barely noticeable mistake in molecule[edit]

I noticed the Chemdraw image on the article on gamma-endorphin is missing an hydrogen of the Valin fragment.

@MadderChemist: You're right. I will fix it soon. Thanks for letting me know. Ed (Edgar181) 20:15, 28 December 2017 (UTC)
Pictogram voting keep.svg Fixed. Ed (Edgar181) 13:14, 4 January 2018 (UTC)

File:Pittsburgh compound B.png[edit]

Hi Edgar181. I'd suggest to re-draw the structure in a way that 11 does not hide the N–C bond. --Leyo 17:35, 24 January 2018 (UTC)

Yes, good suggestion. I have replaced it with File:Pittsburgh compound B.svg. Thanks, Ed (Edgar181) 17:49, 24 January 2018 (UTC)
Thank you. --Leyo 00:45, 25 January 2018 (UTC)

Your archive for 2017 goes to 2016[edit]

Had to type it in manually to get to our old analogs. Only have a very few left:

Cocaine & Phenyltropanes

Benztropines & GBRs

UMB38 and chloro-substituted analogues (An R-substitution image for)

Then that's it, wouldn't even be the biggest deal in the world if you never got around to them, the first one is the only one really that goes to my cocaine analogues page to the ends of any exhaustive completeness, everything else is just as an aside. Nagelfar (talk) 01:11, 27 January 2018 (UTC)

@Nagelfar: I didn't realize that there were some not done yet. All these are done now and can be found in my recent uploads. And I've corrected my archive link. Ed (Edgar181) 14:28, 27 January 2018 (UTC)
Thanks! I mistyped with one though, I meant an R subst. image for the AHN, JHW, GA class, not the MFZ since you got the two MFZ and there were so many more of the others. Thanks Ed! Nagelfar (talk) 20:31, 27 January 2018 (UTC)
OK, here's an image for that series: File:AHN-JHW-GA series.svg. Ed (Edgar181) 11:32, 28 January 2018 (UTC)
LOL I think we're good, I just noticed I already had it; duh, my fault there: File:Cocaine_analog_260-265.svg, OK, sorry about that, thanks for all the rest. Nagelfar (talk) 20:55, 28 January 2018 (UTC)

structure File:Polinoxilina.png[edit]

That's the structure provided by Avogadro(R) according to the SMILES here and here. Avogadro(R) created the structure with translation made in here.StormBringer (talk) 17:10, 31 January 2018 (UTC)

@StormBringer: PubChem is full of chemical structure errors. Structures, SMILES, and other data are machine-generated and not well curated. In particular, PubChem does not handle polymers or other complex chemical structures well. Polinoxilina (polynoxylin) is a polymer, not individual units of formaldehyde and urea. Ed (Edgar181) 17:28, 31 January 2018 (UTC)
I uploaded a new version of thefile. Check it out, please.StormBringer (talk) 18:09, 31 January 2018 (UTC)
In my opinion, that is a little confusing. I wonder if something akin to these examples, File:Polyoxymethylene 3D spacefill.png or File:Polyethylene-terephthalate-3D-spacefill.png, might work better, where the viewer is looking at a section of a chain that extends beyond the borders of the image. In any case, I have removed the {{disputed chem}} template. Thanks for the quick update. Ed (Edgar181) 18:42, 31 January 2018 (UTC)


El tiocarbamato está entre el oxígeno y el nitrógeno. Pero por alguna razón el color amarillo no registro apropiadamente. Se cambió por otra estructura a partir del mismo archivo MOL. Gracias.StormBringer (talk) 16:07, 10 February 2018 (UTC)

Thank you for the quick fix. Ed (Edgar181) 16:15, 10 February 2018 (UTC)

request for svg image[edit]

When you get a chance can you make a replacement for File:Preparation of carbaryl as in Bhopal.png (change the n-ch3 fragment of carbaryl in the image to NMe)

Mfernflower (talk) 18:07, 5 March 2018 (UTC) Mfernflower (talk) 18:07, 5 March 2018 (UTC)

In general, the use of "Me" isn't favored in chemical structure images on Wikipedia because in German "Me" is used to indicate "metal". Would you be OK with an image that uses "CH3" instead? Ed (Edgar181) 20:58, 5 March 2018 (UTC)


Clear copyvio case, please look into this [1]. Flickr Acc made to just put up this photo. Request for speedy deletion ( 19:43, 5 March 2018 (UTC))

✓ Done. Ed (Edgar181) 20:53, 5 March 2018 (UTC)

The factual accuracy of the chemical structure File:Norclostebol.svg is disputed[edit]

Dispute notification The chemical structure File:Norclostebol.svg you uploaded has been tagged as disputed and is now listed in Category:Disputed chemical diagrams. Files in this category are deleted after one month if there is no upload of a corrected version and if there is no objection from the uploader or other users. Please discuss on the file talk page if you feel that the dispute is inappropriate. If you agree with the dispute, you can either upload a corrected version or simply allow the file to be deleted.

In all cases, please do not take the dispute personally. It is never intended as such. Thank you! --Jynto (talk) 16:15, 25 March 2018 (UTC)

Thanks for catching the error. It's now fixed. Ed (Edgar181) 19:20, 25 March 2018 (UTC)


Hello Edgar, I noticed your graphics work on Tebufenozide, and wondered if you might do the same to Dibenzoylhydrazine, seeing as it is very similar. Thanks in advance. Magnoffiq (talk) 00:25, 30 April 2018 (UTC)

@Magnoffiq: No problem, here it is: File:Dibenzoylhydrazine.svg. Ed (Edgar181) 11:24, 30 April 2018 (UTC)
Thank you, @Edgar181:. Magnoffiq (talk) 13:27, 30 April 2018 (UTC)


Hi. I noticed that you recently fixed the bond angles in this structure. They did indeed need fixing but at the same time the benzene ring was substituted for pyrimidine ring. I would fix it myself I don't currently have a vector graphics program (maybe I should give Inkscape a try). I know that ChemDraw has the option to save file as .svg but to my experiences it leads to weird problems when saved to Commons. --MiPe (talk) 09:40, 30 August 2018 (UTC)

Yes, you are right. I have now corrected the image. Thanks for catching the error and letting me know. Ed (Edgar181) 12:10, 30 August 2018 (UTC)
