Nitrazine Yellow Chemical Properties,Usage,Production
Chemical Properties
bordeaux to brown powder, soluble in water, dilute acid and dilute alkali. The maximum absorption wavelength is 586nm.
Uses
Nitrazine Yellow is a pH-sensitive azo dye. It changes color from yellow to blue in pH range 6.0–7.0 and is widely used in microscopy. Dyes and metabolites.
Application
Nitrazine Yellow is used to test vaginal pH during late pregnancy to determine the breakage of the amniotic sac. To perform a fecal pH test for diagnosing intestinal infections or other digestive problems. In civil engineering, to determine the carbonatation spread in concrete structures and therefore assess the state of the rebar's passivation film.
