5-bromo-3-nitro-o-xylene - Introduction
It is an organic compound. Its chemical formula is C9H10BrNO3 and its molecular weight is 258.09. It is a yellow crystal with a strong pungent odor.
The following is a detailed description of the nature, use, preparation and safety information of:
Nature:
is a flammable organic compound. It has a melting point of 82-85 degrees Celsius and a boiling point of 107-108 degrees Celsius. The compound is stable at room temperature, but there is a risk of explosion in the presence of high temperatures, fire sources or organic substances. It is insoluble in water, but soluble in many organic solvents such as alcohols and ethers.
Use:
It is mainly used as an important intermediate in organic synthesis. It can be used in the synthesis of pesticides, dyes, pharmaceuticals and other organic compounds. Due to its anti-biological activity, it is also used as a component of insecticides and fungicides.
Method:
The phosphonium can be synthesized by Bromination and nitration of 2,3-dimethylphenol. First, 2,3-dimethylphenol is reacted with a brominating agent such as bromine under acidic conditions to give 2,3-dimethyl-5-bromophenol. Then, 2,3-dimethyl-5-bromophenol is reacted with a nitrating agent such as nitric acid in the presence of sulfuric acid to obtain phosphonium.
Safety Information:
Irritating and corrosive to skin, eyes and respiratory tract. Wear appropriate protective equipment such as protective gloves, goggles and protective masks when using or handling this compound. Avoid contact with skin and inhalation of vapors. In addition, operate in a well-ventilated place, away from fire and high temperature. Avoid contact with oxidizing agents, reducing agents and flammable materials to prevent fire and explosion. In the process of handling, please follow the correct experimental operation procedures and safe operation methods.
