Fast Blue RR salt Usage And Synthesis

Chemical Properties

Khaki powder

Uses

Fast Blue RR Saltn is a useful dye to detect alkaline phosphatase and nonspecific esterase.

Uses

Fast Blue RR Salt is used in identifying pharmaceutical detection in urine.

Biological Activity

Fast blue RR is mainly used in histological stainings. It binds to the reaction product of alkaline phosphatase and precipitates it as an insoluble compound. The sites of alkaline phosphatase activity appears black. Fast blue RR is also used for the detection of esterase activity. It couples with naphthol (released from naphthol acetate) and forms an insoluble azo-dye which appears red/blue.
