CAS:Nitrazine Yellow is a reversible, reusable, imine-based fluorescent dye that absorbs in the near-infrared region of the spectrum. This compound has been shown to be an acceptor and an inorganic amide. Nitrazine Yellow also has transition metal properties and is a heterocyclic ring. It can be used as a hydrogen bond donor or proton acceptor, depending on its environment. Nitrazine Yellow can react with hydroxylamine to form coupler products that are metastable and can be detected by fluorometric analysis.Formula:C16H8N4Na2O11S2Purity:Min. 95%Color and Shape:PowderMolecular weight:542.37 g/molNitrazine Yellow
CAS: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. This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.Formula:C16H8N4Na2O11S2Color and Shape:Yellow to brown, PowderMolecular weight:542.36
