1-Naphthyl acetate is a 1-napthyl ester. Mechanism of photo-Fries rearrangement of 1-naphthyl acetate has been studied using steady state photolysis and laser flash photolysis. 1-Naphthyl acetate is a 1-napthyl ester. Mechanism of photo-Fries rearrangement of 1-naphthyl acetate has been studied using steady state photolysis and laser flash photolysis. Usually used in a rapid staining method for identification of macrophages; counts by this method were confirmed by the more complex morphological criteria, by phagocytosis, and by the presence of Fc receptors. product description： 1-Naphthyl acetate is a 1-napthyl ester. Mechanism of photo-Fries rearrangement of 1-naphthyl acetate has been studied using steady state photolysis and laser flash photolysis. Kinetics of photo-Fries rearrangement of 1-napthyl acetate has been studied using steady-state, time-resolved chemically induced dynamic nuclear polarization (CIDNP) and flash photolysis methods.
