I've updated the military specification for UDMH with a reference and link. Bosef1 (talk) 03:16, 22 May 2011 (UTC)Reply[reply]

The link for UDMH contaminating apple juice needs to be fixed.

Can anyone shed light on why the name is unsymmetrical and not the generally more standard asymmetrical? Sbreheny (talk) 07:35, 25 December 2014 (UTC)Reply[reply]

The New York Times has an article about North Korea's use of UDMH in its rockets. It points out that the substance is very toxic and very difficult to use safely as a fuel. It also points to a story about a 1960 rocket explosion in the Soviet Union (now the Baikonur complex in Kazakhstan) which killed an estimated 150 people. That led them to reduce their use of UDMH. https://www.nytimes.com/2017/09/17/world/asia/north-korea-rocket-fuel-missiles.html?hp&action=click&pgtype=Homepage&clickSource=story-heading&module=first-column-region&region=top-news&WT.nav=top-news Isdnip (talk) 14:43, 18 September 2017 (UTC)Reply[reply]

Rocket fuels, by definition, are dangerous materials, so no news there. --Smokefoot (talk) 14:47, 18 September 2017 (UTC)Reply[reply]

Hello fellow Wikipedians,

I have just modified one external link on Unsymmetrical dimethylhydrazine. Please take a moment to review my edit. If you have any questions, or need the bot to ignore the links, or the page altogether, please visit this simple FaQ for additional information. I made the following changes:

• Added archive https://web.archive.org/web/20030207030254/http://www.astronautix.com/props/n2o4udmh.htm to http://www.astronautix.com/props/n2o4udmh.htm

When you have finished reviewing my changes, you may follow the instructions on the template below to fix any issues with the URLs.

It has been proposed in this section that Unsymmetrical dimethylhydrazine be renamed and moved to Asymmetric dimethylhydrazine. A bot will list this discussion on requested moves' current discussions subpage within an hour of this tag being placed. The discussion may be closed 7 days after being opened, if consensus has been reached (see the closing instructions). Please base arguments on article title policy, and keep discussion succinct and civil. Please use ((subst:requested move)). Do not use ((requested move/dated)) directly.

Unsymmetrical dimethylhydrazine → Asymmetric dimethylhydrazine – Unsymmetrical->Asymmetric: More standard term Jeaucques Quœure (talk) 18:04, 13 February 2024 (UTC) — Relisting. Bensci54 (talk) 20:31, 21 February 2024 (UTC)Reply[reply]

• Oppose: This is what it is called - it isn't than a name that wikipedia has invented. The reason for the odd choice is actually to reduce confusion, because in chemistry 'asymmetric' very often refers to chirality and unsymmetrical dimethylhydrazine isn't chiral. --Project Osprey (talk) 20:49, 21 February 2024 (UTC)Reply[reply]
• Oppose. "Unsymmetrical dimethylhydrazine" appears to be the much more standard term based on a search for both chemical names in SciFinder (largest database of chemical literature). Google and Google Scholar searches give the same result. Creating a redirect from Asymmetric dimethylhydrazine is probably a good idea though because that term is used.

• Oppose as the current name is the common one. Graeme Bartlett (talk) 21:58, 21 February 2024 (UTC)Reply[reply]
• Oppose - "UDMH" is a very commonly used acronym. (— 𝐬𝐝𝐒𝐝𝐬 — - talk) 22:00, 21 February 2024 (UTC)Reply[reply]
