3,5-二氟苯基乙醇酸 - Introduction
3,5-Difluoromandelic acid is an organic compound. The following is a description of its nature, use, formulation and safety information:
Nature:
-Appearance: 3,5-Difluoromandelic acid is a colorless to pale yellow solid.
-Solubility: It can be dissolved in water and has good solubility in organic solvents.
-Melting point: Its melting point is about 150-155°C.
-Chemical properties: 3,5-Difluoromandelic acid is a strong acid that can react with alkali to form the corresponding salt.
Use:
- 3,5-difluoromandelic acid is widely used in organic synthesis. It can be used as an acid catalyst to catalyze various organic reactions, such as esterification, alcohol condensation, oximation and acetal reactions.
- 3,5-Difluoromandelic acid can also be used as a raw material for fungicides and insecticides.
Preparation Method:
- 3,5-Difluoromandelic acid can be prepared by reacting 3,5-difluorobenzoic acid with an inorganic acid (such as sulfuric acid). The reaction is generally carried out in an inert solvent and isolated and purified by distillation.
Safety Information:
- 3,5-difluoromandelic acid is relatively stable under general conditions. However, since it is a strong acid, care should be taken during use and storage. Avoid contact with skin, eyes and respiratory tract. Wear appropriate protective equipment such as gloves and goggles during use.
