Einecs 221-616-8 - Introduction
4-Nitrobenzene-1,3-diol is an organic compound with the chemical formula C6H5(NO2)(OH)2. The following is a description of its nature, use, preparation and safety information:
Nature:
- 4-Nitrobenzene-1,3-diol is a colorless crystalline solid that can be dissolved in water and organic solvents.
-It has phenoxy and nitro functional groups, so it has the characteristics of phenol and nitro compounds.
Use:
- 4-Nitrobenzene-1,3-diol is widely used in organic synthesis. Due to the existence of nitro and hydroxyl groups, it can be used as a reagent for alkylation, phenol-formaldehyde condensation, nucleophilic substitution and other reactions.
-It can also be used for the preparation of photochromic materials, dyes and fungicides.
Preparation Method:
- 4-Nitrobenzene-1,3-diol can be prepared by nitration of p-nitrophenol. First, nitrobenzene and concentrated sulfuric acid are mixed, heated to an appropriate temperature, and after a period of reaction, water is added to stop the reaction. After that, 4-Nitrobenzene-1,3-diol was obtained by crystallization purification.
Safety Information:
- 4-Nitrobenzene-1,3-diol is dangerous and should be handled with care.
-It may cause irritation or damage to the eyes, skin, respiratory and digestive systems.
-Wear appropriate protective equipment such as gloves, glasses and protective clothing during use or handling.
-Avoid inhaling its dust or contact with the skin.
-If inhaled or ingested by mistake, seek medical attention immediately and explain to your doctor with a label on the packaging or chemical.
