GENERAL DESCRIPTION & APPLICATIONS

Mononitrophenols are used as intermediates for the synthesis of a number of organophosphorus pesticides, azo dyes, and some medical products as well as their corresponding amonophenols by reduction. some end products derived from mononitrophenols include dyes and pigments, acetaminophen (from p-aminophenol), carbofuran, phosalon (insecticides form o-nitrophenol), parathion,parathion-methyl, fluorodifen (insecticides form p-nitrophenol), nitrofen, bifenox (herbicides form p-nitrophenol), fungicides, and rubber chemicals. Nitrophenol is used as a pH range indicator (colorless at 5 and yellow at 7). Nitrophenol derivatives are used as intermediates for the synthesis of a number of target products.
