Ghoneim, Mohamed M. published the artcilePolarographic reduction of phenolphthalein, cresolphthalein, thymolphthalein, and α-naphtholphthalein in aqueous and nonaqueous ethanolic solutions, Name: 3,3-Bis(4-hydroxynaphthalen-1-yl)isobenzofuran-1(3H)-one, the publication is Canadian Journal of Chemistry (1979), 57(11), 1294-8, database is CAplus.
The polarog. reduction of phenolphthalein, cresolphthalein, thymolphthalein, and α-naphtholphthalein was studied in ethanolic Britton-Robinson buffer series (pH 2-12), nonaqueous ethanolic medium, and aqueous EtOH. The compounds are reduced through a single 2-electron wave in nonaqueous medium, and aqueous buffered solutions of pH <9 or 1-electron steps for pH >9. The nature of the waves, mechanism of the electrode reaction, and kinetic parameters are considered.
