134604-07-2 - Introduction
2-Bromo-5-nitrobenzonitrile is an organic compound with the chemical formula C7H4BrNO2.
Nature:
2-Bromo-5-nitrobenzonitrile is a solid substance, colorless or light yellow, with a special smell. It has a high melting point and boiling point, insoluble in water, but soluble in many organic solvents, such as ethanol and dimethylformamide. The compound is sensitive to light and should be kept away from light and heat sources.
Use:
2-bromo-5-nitrobenzonitrile is commonly used as a reagent in organic synthesis reactions. It has important applications in drug synthesis, dye synthesis and other organic synthesis fields. Such compounds are commonly used in the preparation of other important organic compounds, such as fluorescent dyes, pesticides and pharmaceutical intermediates.
Preparation Method:
Generally, the preparation method of 2-bromo-5-nitrobenzonitrile is obtained by a substitution reaction of heptanobenzene. The specific preparation method includes reacting heptanobenzene with bromine and nitric acid to form 2-bromo-5-nitrobenzoic acid, which is then converted to 2-bromo-5-nitrobenzonitrile by acyl chlorination and cyanation.
Safety Information:
2-Bromo-5-nitrobenzonitrile is an organic compound with certain toxicity. Its contact or inhalation may cause irritation and damage to human body. Appropriate personal protective equipment such as chemical goggles, protective gloves and protective clothing should be worn during handling. In addition, the compound should be stored in a cool, dry and well-ventilated place, away from fire and heat sources. Use should be careful to avoid dust and particles.
