Diethazine, trifluoperazine, promethazine, and chlorpromazine hydrochlorides, butaperazine dimaleate, and prochlorperazine maleate were studied as indicators in the BrO3- titration of quinol, metol, and ascorbic acid. Their formal potentials were determined They are superior to p-ethoxychrysoidine and 2,6-dichlorophenolindophenol as indicators because they give sharper and brighter end points, the end point color is more stable, and a slight excess of BrO3- after the equivalence point does not destroy the color. In all the BrO3- titrations of quinol, metol, and ascorbic acid, these indicators gave results accurate to ±0.2%.
