Abstract
Abstract A kinetic-spectrophotometric study is performed on the formation and degradation of the isoindole derivatives of amino acids with o -phthalaldehyde and N -ace-tyl- l -cysteine. The experimental and structural factors which affect the formation and stability of the compounds are considered, and the results are compared with those obtained for mercaptoethanol. N -Acetyl- l -cysteine derivatives are highly stable, not requiring a strict control of the time of reaction as in the case of mercaptoethanol.
