1. 4-hydroxy-2-oxovalerate
2. 2'-aminobiphenyl-2,3-diol
3. 2-hydroxy-6-oxo-6-(2'-aminophenyl)-hexa-2E,4Z-dienoate
4. 2-hydroxypenta-2,4-dienoate
5. Cis-2-hydroxy-penta-2,4-dienoate
6. 2-hydroxy-cis,cis-muconate semialdehyde
7. Cis-2-hydroxypenta-2,4-dienoate
These are reported metabolites of carbazole which are produced by bacteria during its biodegradation. I need to know the mass spectra of the compounds to identify the metabolites after running the degraded samples in HR-LCMS. It will be great help if anyone can help me to get the spectra at least of the first 3 compounds.
Thanks in advance
