Nature:
-Appearance: 5-(4-nitrophenyl)furfural as a yellow crystalline or pale yellow solid.
-Solubility: It is soluble in organic solvents such as ethanol, methanol and chloroform, but insoluble in water.
-Melting point: Its melting point is 64-66 degrees Celsius.
-Stability: It is relatively stable at room temperature.
Use:
-Chemical reagent: 5-(4-nitrophenyl)furfural can be used as an organic synthesis reagent for the synthesis of other compounds.
-Dye: It can be used as a synthetic intermediate for organic dyes.
-Photosensitive material: Because its structure contains aromatic rings and nitro functional groups, it can be used to prepare photosensitive materials, such as photosensitive paper or photosensitive films.
Preparation Method:
5-(4-nitrophenyl)furfural is mainly synthesized by the following steps:
-First, 4-nitrobenzaldehyde (4-nitrobenzaldehyde) and furan (furan) are reacted to obtain 4-nitrophenylfurfural (4-(4-nitrophenyl)furfural).
-Then, 4-nitrophenylfurfural is subjected to hydrogenation reduction reaction to remove the nitro functional group and obtain 5-(4-nitrophenyl)furfural.
Safety Information:
-Handle 5-(4-nitrophenyl)furfural carefully to avoid contact with skin, eyes and respiratory tract.
-Wear appropriate personal protective equipment, such as acid-resistant gloves and protective glasses, when in use.
-During storage or operation, avoid contact with oxidants or flammable materials to prevent fire or explosion.
