What is p-Nitrophenol?

Para-Nitrophenol,also called p-nitrophenol or 4-Nitrophenol, is a phenolic compound

that has a nitro group at the opposite position of hydroxyl group on the benzene ring. 4-Nitrophenol shows two polymorphs in the crystalline state. The alpha-form is colorless pillars, unstable at room temperature, and stable toward sunlight. The beta-form is yellow pillars, stable at room temperature, and gradually turns red upon irradiation of sunlight. Usually 4-nitrophenol exists as a mixture of these two forms.

Application of 4-Nitrophenol

p-Nitrophenol is an intermediate in the synthesis of paracetamol. It is reduced to 4-aminophenol, then acetylated with acetic anhydride.

p-Nitrophenol is used as the precursor for the preparation of phenetidine and acetophenetidine, indicators, and raw materials for fungicides. Bioaccumulation of this compound rarely occurs.

In peptide synthesis, carboxylate ester derivatives of 4-nitrophenol may serve as activated components for construction of amide moieties.

It is used as a pH indicator, turning from colorless or pale yellow to a bright yellow at pH greater than 6

-- Used as important raw materials of organic synthesis.

-- Used as raw materials and intermediates of pesticide,such as intermediates of organophosphorus pesticides, 

parathion methyl parathion,etc.

-- Used as as raw materials and intermediates of medicines,such as phenacetin, paracetamol,etc.

-- Used as raw materials of Dye intermediates,such as Developer m tall, sulphur grass-green designed.the GN, sulfide reduction black CL, reversion of black CLB, red brown B3R sulfide reduction blue RNX, sulfide,etc.

-- Used as Leather preservatives.

Packing mode of 4-Nitrophenol

-- 50kg bag, total 20 MT per 20ft container with pallets.

-- 25kg fibre drum, total 9 MT per 20ft container with pallets,12 MT without pallets.
