2-Fluorobenzoic hydrazide,2 Flurobenzhydrazide - Introduction
2-Fluorobenzoic hydrazide(2-Fluorobenzoic hydrazide) is an organic compound with the chemical formula C7H6FN3O.
Nature:
2-Fluorobenzoic hydrazide is a colorless solid with strong amino properties. It is insoluble in water at room temperature, but can be dissolved in some organic solvents such as ethanol and dimethyl sulfoxide.
Use:
2-Fluorobenzoic hydrazide are commonly used in organic synthesis as intermediates in the synthesis of other organic compounds. It can be used to synthesize drugs, dyes, pesticides and other compounds.
Preparation Method:
2-Fluorobenzoic hydrazide can be prepared by the reaction of 2-fluorobenzoic acid and hydrazine. The specific preparation method is as follows:
1. Mix 2-fluorobenzoic acid and hydrazine in molar ratio.
2. Add an appropriate amount of acetic acid as a solvent and catalyst to this mixture.
3. The reaction mixture is allowed to react under appropriate reaction conditions, such as heating or stirring.
4. After completion of the reaction, a 2-Fluorobenzoic hydrazide product was obtained by cooling or filtration.
Safety Information:
2-Fluorobenzoic hydrazide require safety during operation and storage. It may be irritating to the eyes, skin and respiratory tract, so wear appropriate protective measures such as goggles, gloves and masks when used. If exposed to the substance, immediately flush the affected area with plenty of water and seek medical help. In addition, it should be used in a well-ventilated place and stored in a dark, dry place.
