Application

Syringaldazine has been used as a substrate to determine the enzymatic activity of the cuticular laccase.

Biochem/physiol Actions

Syringaldazine is a dimer of two molecules of 2,6-dimethoxyphenol linked by an azide bridge. It is a phenolic non-autooxidizable laccase-specific compound, that facilitates the detection of fungal laccase in some varieties of fungi. In addition, it also acts as an indicator for peroxidase activity in fungi.
