APPLICATIONS: Analytical reagent,
Synthesis reagent: Depending on reagents and conditions used , reduction of aromatic nitrocompounds leads to different products. Reducing agents such as palladium 5% on activated carbon , tin (II) chloride , sodium borohydride , etc., have been used ·Reduction to phenylhydroxylamine by zinc and ammonium chloride and sub-sequent partial reoxidation with dichromate gives nitrosobenzene ·Reduction to phenylhydroxylamine with hidrazine hydrate in the presence of rhodium on charcoal , ·Reduction to azobenzene with arsenic (III) oxide ·Reduction to azobenzene with zinc and sodium hydroxide ·Used as an oxidant in the Skraup synthesis of quinolines ·The deactivated aromatic rings undergoes electrophilic substitution at the 3-position. Monobromination in the presence of aluminium chloride · Used as a solvent for the aluminium chloride-induced Pechmann reaction of phenol with ethyl acetoacetate , to give 4-methylcoumarine
