Application

2-Nitro-1-naphthol was employed as substrate for use in an amperometric 3-electrode system for the determination of alkaline phosphatase, the enzyme label most commonly used in electrochemical immunoassays. It was also used in the preparation of:
  • di-(2-nitro-1-naphthyl) hydrogen phosphate
  • 1-(2′-methyl-3′-indenyl)-2-naphthylamine and -2-naphthol (axially chiral ligands)
