Description

Bromopyrogallol red is a photochemical reagent that can be used as an optical sensor for nitrite ions. The substance reacts with nitrite ions to produce a stable complex, which has a strong absorption in the visible region of the spectrum. This reaction mechanism is based on the photochemical properties of bromopyrogallol red and its ability to form stable complexes with nitrite ions. Bromopyrogallol red can be used as a sample preparation agent in analytical methods for measuring nitrite ion concentration in wastewater treatment and human serum samples. It is also useful in measuring the amount of nitrites produced by stomach acid hydrolysis.
