Additional information:
Long chain aldehydes may be formed in the GC injector from 3-hydroxy FAME with two more carbons. See H. Husmann et al, J. Sep. Sci. 13 (1990) 780-782. 3-hydroxyeicosanoic acid acid is therefore listed as the non-derivatized (parent) compound of octadecanal.

Non-derivatized:
