The conversion of a sulfydryl group of mercaptoacids to a thiuronium group by means of dimethylcynamide followed by electrophoresis on cellulose gel strips is suggested as a method for estimation of the number of carboxyl groups in the molecule and for separation of mono and polycarboxyl mercaptoacids. As a result of cyanamidation the molecule gains an additional positive charge reflected in a shift of pH‐mobility curves along the mobility axes.
