Atmospheric pressure chemical ionisation reversed‐phase high‐performance liquid chromatography/multistage mass spectrometry has been used to study the mass spectral fragmentation of the cyanobacterial sheath pigment scytonemin and its reduced counterpart. The two pigments exhibit characteristic fragment ions in their MS 2 and MS 3 spectra that are of value in confirming the identification of the structures in extracts from natural environments.
