German term

2,3-Methylbutanal

German to English Tech/Engineering Chemistry; Chem Sci/Eng aroma substances - carbonyl compound
I cannot find any native EN/US reference for 2,3-methylbutanal or 2/3-methylbutanal, all seem to be translations from German or French.

Can anyone confirm that it might be 3-methyl-2-butanal?

TIA
Proposed translations (English)
4 2/3-methyl butanal

Rainer nochmals danke. Mich hatte das Deutsche verwirrt und ich habe einfach nicht klar gesehen. Der ganze Artikel war einfach schlampig geschrieben.

@ Edith: Gern geschehen! Mit weihnachtlichen Grüßen ;-)
Edith Kelly (asker) Dec 20, 2013:
Rainer stimmt was du sagst. Absolut korrekt. Ich habe es auseinandergenommen und als 2-Methylbutanal und als 3-Methylbutanal geschrieben. Übrigens, ich bin mit einem englischen Muttersprachler Chemiker verheiratet. Ich danke dir für die Warnung. Aber 2/3 bedeutet wohl: es ist 2 als auch 3. Ganz herzlichen Dank und die üblichen Weihnachtswünsche..

critical eye of a chemist Do not add to the glossary! There is no such thing as 2/3-methylbutanal in chemistry. You either get 2-methylbutanal or 3-methylbutanal or a mixture of the two - spelled out as '2-methylbutanal and 3-methylbutanal' and nothing else! Unfortunately I have seen shortcuts such as 2-/3-methylbutanal, but I would not use them in a specialist context. Then you get 2,3-dimethylbutanal i.e. butanal with two Me groups attached to the 2- and 3-positions.
@ Edith: make quite sure what the source text says - if there is still time, that is.
Good job Yorkshireman That makes sense, it meaning two compounds. With a comma it would refer to two methyl groups and be called 2,3-dimethylbutanal. (See http://www.chemspider.com/Chemical-Structure.92814.html )
Edith Kelly (asker) Dec 19, 2013:
Got it it is indeed 2/3 methyl butanal as reference is also made to 2-Methylbutanal and 3-Methylbutanal individually. The German is confusing.

Cheese thanks, why not post as an answer

2/3-methyl butanal

As suggested in the discussion box. A very "cheesy" substance.

disagree rainerc (X) : see my discussion entry / chemistry is not everybody's slice of cheese - or is it cup of tea ? ;-)

Please take it up with the cheese-makers - I admit that I know much more about cheese than chemistry. @Rainer - I fear to think what things may be in both cheese and tea :-) But whatever there is is very probably from Mon..nto!
Something went wrong...
