Application

  • 2-Nitrophenol can be used in the iron-catalyzed synthesis of 2-arylbenzoxazole from benzylic alcohols.
  • It is employed in the preparation of heterodiazocines, which are potential photochromic compounds for applications in photopharmacology and functional materials.
  • It can be used as a precursor in synthesizing “off-on” chemosensor for Hg2+ detection in aqueous acetonitrile solution.
  • Additional application includes the synthesis of 1,4-benzoxazine derivative in the total synthesis of antimicrobial agent, levofloxacin.

Physical form

Due to its specific melting range the product may be solid, liquid, a solidified melt or a supercooled melt.

Nitrophenols and methylnitrophenols have been identified as photolytic precursors of nitrous acid, HONO, but their gas-phase absorption has not previously been reported. In this study, the absorption cross sections of 2-nitrophenol, 3-methyl-2-nitrophenol, and 4-methyl-2-nitrophenol were measured from 320 to 450
