Benzenepropanoic acid, 4-broMo-, ethyl ester - Introduction
Ethyl bromobenzoate (3-(4-Bromophenyl)propionic acid ethyl ester) is an organic compound with the chemical formula C11H13BrO2.
Nature:
Ethyl bromobenzene propionate is a colorless to pale yellow liquid with a special odor. It has a density of 1.31g/cm³ and a boiling point of about 290°C. Ethyl bromobenzopropionate is insoluble in water at normal temperature, but soluble in organic solvents such as ethanol and dimethylformamide.
Use:
Ethyl bromobenzene propionate is a common organic synthesis intermediate. It is often used to synthesize organic compounds such as pharmaceuticals, pesticides and dyes.
Preparation Method:
The preparation of ethyl bromobenzene propionate can be carried out by the following steps:
1. Benzoic acid is reacted with bromine to obtain bromobenzoic acid.
2. Bromobenzoic acid is reacted with helium ketone to obtain acid anhydride.
3. Finally, the acid anhydride is reacted with ethanol to obtain ethyl bromobenzene propionate.
Safety Information:
Ethyl bromobenzene propionate is irritating and corrosive. During use, direct contact with skin, eyes and mucous membranes should be avoided. Wear appropriate personal protective equipment, such as gloves, glasses and protective clothing. Good ventilation should be provided during use. If exposed or inhaled, wash the affected area immediately and seek medical advice.
