Drug Information

MeSH：

Colorless, endogenous or exogenous pigment precursors that may be transformed by biological mechanisms into colored compounds; used in biochemical assays and in diagnosis as indicators, especially in the form of enzyme substrates. Synonym: chromogens (not to be confused with pigment-synthesizing bacteria also called chromogens). (See all compounds classified as Chromogenic Compounds.)

MeSH Entry Terms：

4-(2-pyridylazo)resorcinol

4-(2-Pyridylazo)resorcinol Use and Manufacturing

Uses

Spectrophotometric determination of transition metal reagents, such as Bi3+, Co2+, Fe3+, Pd 2+, Ni2+, NbO, In3+, La3+, Tn4+, plasma developer. EDTA is combined with titration to measure Al3+, Bi3+, Ca3+, Cu2+, Ga7+ and other metal indicators, and lead nitrate solution precipitation titration of indicators such as MoO, PO and WO.
