Structure analysis of phosphorus compounds within the framework of the Chemical Weapons Convention requires the specific identification of alkyl substituents on phosphorus. In this work the distinction of the P-propyl substituent in propylphosphonic acid derivatives by electrospray tandem mass spectrometry was investigated. P-Isopropyl and P-n-propyl groups were readily distinguished and a mechanistic proposal was given, based on labelling experiments, The findings were applied to the identification of the P-propyl moiety of two V-agents, O-ethyl S-[2(dialkylamino)ethyl]propylphosphonothiolates, and to a degradation product of a G-agent, propyl propylphosphonate. © 1998 John Wiley & Sons, Ltd. |
