A novel mechanism is proposed for the alkali‐induced transformation of thiamine; it is based on the results of kinetic investigations. The time‐dependent UV spectra of alkaline thiamine solutions, whose yellow color rapidly disappears, reveal isosbestic points, thus indicating that no intermediate is formed in significant amounts.
