| 摘要 |
The present invention provides a novel group of protein error indicators including nitro or nitroso substituent groups in the B and C rings of a partially halogenated triphenylmethane compound. Di-nitro or nitroso substituted protein error indicators of the present invention are represented by the structural formula: <CHEM> wherein: X is -Cl, -Br, -I; Y is -NO2 or -NO; and Z is -Cl, -Br, -I. Mono-nitro or nitroso protein error indicator compounds of the present invention are illustrated by the following formula: <CHEM> wherein: X is -Cl, -Br, -I; Y' is -NO2 or -NO; Y'' is -Cl, -Br, -I; and Z is -Cl, -Br, -I. |
