CAS:3-Hydroxy-4[2-sulfo-4-(4-sulfophenylazo)phenylazo]-2,7-naphthalenedisulfonic acid tetrasodium salt is a chemical compound that has been used in the diagnosis of proteinuria. It reacts with the α1-acid glycoprotein to form a ponceau dye. The 3HSA can be detected by fluorescence probe, which binds to the sulfonate group on the dye. The reaction mechanism of 3HSA is shown below: 3HSA + α1AG → ponceau dye + H+ + AG The chemical properties of 3HSA are as follows: pK = 12.6 logP = 2.6 Baume = 13.6 Tm = -5°C ΔG° (298 K) = -0.8 kJ/molFormula:C22H12N4O13S4Na4Purity:Min. 95%Color and Shape:Red PowderMolecular weight:760.57 g/mol
