The leuco quinoneimine dyes are unstable to isolate but the substitution of an electron-withdrawing group such as acyl,13 carbamoyl,13 carboxy,13 or arylsulfonyl 12 group at the amino nitrogen atom stabilizes the... [Pg.53]

Glucose (65) kits Commercial kits are based on the enzymatic process shown in equation 16, followed by a chromogenic oxidation process catalyzed by peroxidase, similar to equation 27, involving 4- aminoantipyrine (81) and a phenol or aniUne derivative, leading to a quinoneimine dye. Among the latter aromatic substrates in use are A -ethyl-Al-(2-hydroxy-3-sulfopropyl)-3, 5- dimethoxyaniline (92) , phenol , p-hydroxybenzoic acid and p-hydroxybenzenesidfonate other chromogenic reactions are peroxidase-catalyzed oxidation of iV,iV,iV, iV -tetramethyl-p-phenylenediamine (89) and D-ditoluidine (93) . d... [Pg.632]

The reduction of hydroperoxides may be coupled with the oxidation of phenol in the presence of 4-aminoantipyrine (81) to yield a quinoneimine dye (186), determined... [Pg.676]
