APPENDIX 
Nomenclature of Polyfunctional Compounds 
 
 
A.1. This compound is a primary amine because there is only one alkyl group attached to the nitrogen, but it also has a hydroxyl 
group. Because alcohol functionalities have a higher suffix priority than amine groups, the compound will be named as an alcohol, 
and the amine will be named as a substituent (an amino group). Referencing Table 4.1, we can infer that an 18-carbon chain is 
called an octadecane, so this alcohol is an octadecanol. Numbering from left to right gives the alcohol and the amine the lowest 
possible numbers. 
 
 
The name so far is 2-amino-3-octadecanol (or 2-aminoctadecan-3-ol using the new IUPAC rules). Lastly, the configuration of each 
chiral center must be specified. 
 
 
 
The full IUPAC name is thus (2S,3R)-2-amino-3-octadecanol.
