1935 Chem. Abstr. 29 6242 When crude lactoflavin is made alk., the fluorescence changes from yellowish green to blue. This phenomenon is due to the presence of a S-contg. pigment for which the name thiochrome is proposed.

1963 Steyn-Parvé & Monfoort in Florkin & Stotz Comprehensive Biochem. XI. i. 16 The thiochrome method is based on the observation..that oxidation with alkaline ferricyanide converts thiamine into a compound with intense blue fluorescence: thiochrome... The thiochrome is extracted..and the fluorescence of the extract measured.
