Abstract:
:Indole-3-acetic acid (IAA) labeled with (13)C in the six carbons of the benzene ring is described for use as an internal standard for quantitative mass spectral analysis of IAA by gas chromatography/selected ion monitoring. [(13)C(6)]IAA was compared to the available deuterium labeled compounds and shown to offer the advantages of nonexchangeability of the isotope label, high isotopic enrichment, and chromatographic properties identical to that of the unlabeled compound. The utility of [(13)C(6)]IAA for measurement of endogenous IAA levels was demonstrated by analysis of IAA in Lemna gibba G-3.
