indophenol

Simple indophenol proper has not yet been isolated.

He identified the gene for indophenol oxidase in mammals.

The formation of indophenol is used to determine ammonia and paracetamol by spectrophotometry.

The oxidized reagent forms the colored compound indophenol blue.

Oxidase-positive bacteria possess cytochrome oxidase or indophenol oxidase (an iron-containing hemoprotein).

He injected the dyes alizarin blue and indophenol blue into laboratory animals and established that after their death various organs had been colored to different degrees.

Dichlorophenol-indophenol (DCPIP), a form of indophenol, is often used to determine the presence of vitamin C, or ascorbic acid.

Likewise, Brewer (1967) identified a protein that later became known as superoxide dismutase as an indophenol oxidase by protein analysis of starch gels using the phenazine-tetrazolium technique.

In organs with high oxygen saturation indophenol was retained; in organs with medium saturation indophenol was reduced, but not Alizarin blue.

This reaction is also used to determine paracetamol in urine samples: After hydrolysis with hydrochloric acid, 4-aminophenol reacts in ammonia solution with a phenol derivate, e.g. salicylic acid, to form an indophenol dye under oxidization by air.
