Non-element organic shorthand

Thomas Winwood - 25-11-2005 at 08:19

This felt a little too general to go in Organic Chemistry, but feel free to move it over if I'm wrong.

I'm accustomed to reading "ethanol" for "EtOH" and "methanol" for "MeOH", but how far do these abbreviations go? Where can I find more information?

I don't have a link, but I've seen isopropanol abbreviated as IpOH

This web-site really needs a page of links to external sites. For instance. Journal abbreviations, named reactions, etc.

A good book is "The Organic Chemist's Desk Reference", P.H. Rhodes which has some pages on compound abbreviations. The standard for these abbreviations is set by Chemical Abstracts.

Ac - acetyl - CH3-CO-
Am - amyl - C5H11-
Bn - benzyl - C6H5-CH2-
Bu - butyl - C4H9-
Bz - Benzoyl - C6H5-CO-
Et - Ethyl - C2H5-
Me - Methyl - CH3-
Ph - Phenyl - C6H5-
Pr - Propyl - C3H7-

nBu - n-butyl
iBu - iso-butyl
sBu - sec-butyl
tBu - tert-butyl

These are the important ones.

Specialists also tend to have their own collection of abbreviations. For example, those in peptide synthesis have stuff like Boc, Fmoc, Cbz (which IIRC is the same as Boc, why'd they make another acronym? :o), and others. Don't forget the abbreviated reagents like PCC, 9-BBN, TMEDA/TEMED, and DEAD as well. :)

Darkblade48, whatever your source was, they should have abbreviated 2-propanol as i-PrOH. :)

Next time you're at a good library, look for a book on total synthesis. They often have several pages of abbreviations at the front for weird protecting groups and such. It's cool to look for the ones whose abbreviations have been influenced by their properties, such as DIE :).

(I can't remember what DIE was now, just that it was rather toxic!)
