Introduction and application of CAS: 975-17-7 | Phenylfluorone
Orange-red crystalline powder. Slightly soluble in water. Slightly soluble in cold ethanol, insoluble in benzene and chloroform. Easily soluble in alkali, easily soluble in acidified ethanol and sulfuric acid solutions, as the pH value of the reagent solution increases, the color changes from yellow to orange to orange-red, and appears purple-red in strong alkali and gradually decomposes. It forms red or purple complexes with Ge4+, Sn4+ plasma in weakly acidic media. The maximum absorption wavelength is 552nm.
Phenofluorenone Usage: Usage: Photometric determination of germanium, molybdenum, niobium, antimony, tin and tantalum, etc. Often used in fuel intermediates or chemical reagents.
