Ethyl 3-(2,4,5-Trifluorophenyl)-3-Oxopropanoate - Introduction
Ethyl 2,4,5-Trifluorobenzoylacetate, also known as ethyl 2,4,5-trifluorobenzoyl acetate (Ethyl 2,4,5-Trifluorobenzoylacetate), its chemical formula is C12H9F3O3. The following is a description of its nature, use, preparation and safety information:
Nature:
Ethyl 2,4,5-Trifluorobenzoylacetate is a colorless to pale yellow liquid with a strawberry aroma. It has a density of 1.36 g/mL, a boiling point of 174-176°C, and a refractive index of 1.477.
Use:
Ethyl 2,4,5-Trifluorobenzoylacetate is commonly used as a reagent and intermediate in organic synthesis. It can be used in the synthesis of aromatic ethyl acetate and other organic compounds. In addition, it can also be used as a surfactant, an optical material and a raw material in the field of medicine.
Preparation Method:
Ethyl 2,4,5-Trifluorobenzoylacetate can be prepared by the following steps:
1. The reaction of 2,4, 5-trifluorobenzoyl chloride and ethanol produces Ethyl 2,4,5-Trifluorobenzoylacetate.
2. Catalyzed by sodium acetate, Ethyl 2,4,5-Trifluorobenzoylacetate was reacted with anhydrous ethanol to obtain the target product.
Safety Information:
Ethyl 2,4,5-Trifluorobenzoylacetate needs to pay attention to the following safety measures when storing and using:
1. Because it is an organic compound, it may be harmful to health. Avoid inhalation, ingestion, or contact with skin and eyes. Wear appropriate protective equipment such as chemical protective gloves, goggles and protective clothing during operation.
2. Use in a well-ventilated place to avoid prolonged contact. Avoid contact with combustion sources to prevent fire or explosion.
3. Waste disposal should be carried out in accordance with local regulations to avoid environmental pollution.
Please note that this is a general introduction, please read the product manual carefully before specific use or operation, and follow the relevant safety procedures and regulations.
