1-fluoro-2-isocyanatobenzene - Introduction
2-Fluorophenyl isocyyanate (2-Fluorophenyl isocyyanate) is an organic compound with the chemical formula C7H4FNO. The following is a description of the properties, uses, preparation and safety information of the compound:
Nature:
2-Fluorophenyl isocyyanate is a colorless liquid with a pungent odor. It is soluble in organic solvents such as ethanol and dichloromethane and insoluble in water.
Use:
2-Fluorophenyl isocyanate is commonly used as a reaction intermediate in organic synthesis. It can be used in the synthesis of other organic compounds, such as esters, amides and ketones.
Method:
2-Fluorophenyl isocyanate is usually obtained by the reaction of 2-fluoroaniline and isocyanate. The reaction is carried out under the protection of inert gas, and the common solvents include dichloromethane and ethanol. After completion of the reaction, a pure product can be obtained by a method such as distillation or extraction.
Safety Information:
2-Fluorophenyl isocyyanate is an irritant compound that can cause irritation and pain on contact with the skin and eyes. Wear appropriate protective equipment such as chemical gloves and goggles during use. In addition, it produces toxic gases when it burns, so contact with strong oxidants or combustibles should be avoided. Storage should be away from fire and high temperature, to ensure a well-ventilated place. In case of leakage or accident, emergency treatment shall be followed. Please read and follow the relevant safety instructions and operating procedures before use and storage.
