对氟苯肼 - Introduction
4-fluorophenylhydrazine is an organic compound with the chemical formula C6H6FN2, which is formed by replacing one hydrogen atom on the benzene ring with fluorine. The following is a description of the properties, uses, preparation and safety information of 4-fluorophenylhydrazine:
Nature:
-Appearance: 4-fluorophenylhydrazine is a colorless to pale yellow solid.
-Melting point and boiling point: The melting point is about 65-70 degrees Celsius, and the boiling point is 120 degrees Celsius.
-Solubility: Soluble in common organic solvents (such as ethanol, acetone, dimethylformamide).
Use:
- 4-fluorophenylhydrazine is commonly used as an amine protecting reagent, a nitrogen source or a condensation reagent in organic synthesis.
-It can be used to prepare laser materials, pesticides and pharmaceutical compounds.
Preparation Method:
The preparation of-4-fluorophenylhydrazine can be completed by the reaction of benzoic acid with ammonia hydrogen fluoride (HF/NH3). First, hydrogen peroxide is added to benzoic acid and hydrochloric acid solution to generate peroxybenzoic acid, and then hydrogen fluoride is added to ammonia to react to obtain 4-fluorophenylhydrazine.
Safety Information:
- 4-fluorophenylhydrazine is a toxic substance that may cause irritation and injury when inhaled or in contact with the skin. Therefore, appropriate protective equipment such as gloves and goggles should be worn during use.
-It should be stored in a dry, well-ventilated place, away from combustibles and oxidants.
-When handling 4-fluorophenylhydrazine, strictly follow safety procedures and ensure that reactions with other chemicals are avoided.
