AdipoGen Chromotropic acid 2Na 2H2O
Chemical. CAS 5808-22-0. Formula HO2C10H4SO3Na2 . 2H2O. MW 364.3 . 36.0. Synthetic. Fluorogenic reagent for analytical the detection of Ag, ClO3-, Cr, Hg, NO2-, NO32-, Ti or CH2O formaldehyde. Quantitative determination of formaldehyde is based on the specific formation of a red coloration peaking at 580 nm wavelength when chromotropic acid in 75% sulfuric acid reacts with formaldehyde. May be employed as a chromogenic reagent for the quantification of dipyrone in various pharmaceutical preparations.
