Mass Spectra of the Hydroxyindole-3-carboxylic Acids and the Hydroxyskatoles Academic Article uri icon

abstract

  • The electron impact fragmentations of the 4-, 5-, 6-, and 7-hydroxyskatoles and the 4-, 5-, 6-, and 7-hydroxyindole-3-carboxylic acids have been studied. The spectra of the four isomeric hydroxyskatoles are virtually indistinguishable, due to substituent randomization of the [M] and [M-1] ions. In the case of the hydroxyindole-3-carboxylic acids, loss of H2O from the molecular ion is characteristic of the 4-isomer but initial loss of OH from the molecular ion is the most important reaction of the other three isomers.
