4-(2-Bromoethyl)-2-oxoindole - Introduction
4-(2 '-Bromoethyl)-1,3-dihydro-2-indolinone, also known as bromopyrrolidone, has the formula C11H12BrNO and a molecular weight of 267.12g/mol.
Nature:
-Appearance: Colorless to light yellow solid
-Melting point: 70-74°C
-Boiling point: 279°C
-Density: 1.35g/cm³
-Insoluble in water, soluble in organic solvents such as ethanol and dichloromethane
Use:
Bromopyrrolidone can be used as an important intermediate in organic synthesis, and has a wide range of applications in the preparation of pesticides, pharmaceuticals and chemicals.
Preparation Method:
Bromopyrrolidine can be prepared by SN2 substitution reaction of pyrrolidone and bromoethane under alkaline conditions. The reaction is usually carried out at room temperature, and the reaction time is short.
Safety Information:
Bromopyrrolidone is irritating to the skin and eyes, and contact with skin and eyes should be avoided. Personal protective equipment such as goggles and gloves are required for operation. During use and storage, keep away from fire sources and high temperature environments, and avoid contact with oxidants and strong acids to prevent dangerous reactions. If accidentally inhaled or ingested, seek medical attention immediately.
