Nucleic Acid Synthesis

(1-AMINO-1-PHOSPHONO-OCTYL)-PHOSPHONIC ACID-

(1-METHYL-HEPTYL)-PHENYL-PHOSPHINIC ACID-

The enantiodiscrimination of (1 R )-(+)-(1-amino-2-methylpropyl)phosphonic acid from its enantiomer in the gas-phase can be done using ESI-MS-CID technique. [electrospray ionization-mass spectrometric detection-collision induced dissociation]
