Pantel, Siegbert published the artcileCatalytic-kinetic determination of substituted thioureas and thioacetamide by an absorptiostat method with bromopyrogallol red/hydrogen peroxide as the indicator reaction, Related Products of catalysis-chemistry, the publication is Analytica Chimica Acta (1984), 158(1), 85-91, database is CAplus.
In the absorptiostat method described, the concentration of the dye in the bromopyrogallol red/H2O2 reaction is kept very low and constant by the automatic addition of increments of bromopyrogallol red solution This is used in aqueous solutions at pH 4.0 to determine the catalyst thiourea, N-methylthiourea, N‘-allylthiourea, and thioacetamide in the 0.1-1 mmol L-1 range with only 0.5-mL samples. The catalytic activities of another nine substituted thioureas are described; they depend on the kind of N-substituents as has been shown before for the NaN3/I2 reaction, but the sequence of activities for different compounds is quite different.
