An ab initio conformational analysis of 4-chloroindole-3-acetic acid was performed at the RHF/6-311G \* \* level. The mirror symmetrical conformer (in which the indole ring is coplanar with the COOH group) is most stable; next in energy are the two conformers with the C-COOH fragment perpendicular t
Oxindole-3-acetic acid (OxIAA) has been identified in germinating seeds of Scots pine (Pinus sylvestris) using gas chromatography-mass spectrometry. Seeds germinated for 5 d contained 2.7 ng OxIAA·g(-1) (dry weight) whereas ungerminated seeds contained 0.2 ng·g(-1). Isotopically labelled OxIAA was f
After oxidation of indole-3-acetic acid with ceric nitrate in the presence of hydroxylamine, a stable colored complex extractable to isoamyl alcohol is formed. This reaction is useful for the calorimetric estimation of indole-3-acetic acid in biological mixtures. The colored complex (whose chromopho
