3-(4-Carboxyphenyl)-5-nitrobenzoic acid - Introduction
5-Nitro-[1,1 '-biphenyl]-3,4'-dicarboxylic acid, also known as 5-Nitro-[1,1 '-biphenyl]-3,4'-dicarboxylic acid, is an organic compound. The following is a description of its nature, use, preparation and safety information:
Nature:
-Appearance: Often a yellow crystalline solid.
-Melting point: about 274-276 degrees Celsius.
-Solubility: Soluble in some organic solvents (such as dimethyl sulfoxide and dichloromethane), but low solubility in water.
Use:
5-Nitro-[1,1 '-biphenyl]-3,4'-dicarboxylic acid can be used as an intermediate in organic synthesis and is widely used in the preparation of dyes, photosensitive substances and polymer materials.
Preparation Method:
5-Nitro-[1,1 '-biphenyl]-3,4'-dicarboxylic acid can be prepared as follows:
1. First, starting from toluene, 1,1 '-diphenylmethane is obtained through an acid-catalyzed oxidation reaction.
2.1,1 '-diphenylmethane reacts with nitric acid to generate 3-(4-hydroxyphenyl)-5-nitrobenzoic acid.
3. Finally, 3-(4-hydroxyphenyl)-5-nitrobenzoic acid was converted to 5-Nitro-[1,1 '-biphenyl]-3,4'-dicarboxylic acid by acid-catalyzed oxidation.
Safety Information:
5-Nitro-[1,1 '-biphenyl]-3,4'-dicarboxylic acid is generally unstable and should be kept in a dry, cool place away from fire and oxidizing agents. Contact or inhalation of the substance may cause irritation to the eyes, skin and respiratory tract, so wear appropriate personal protective equipment and ventilation equipment when used.
