4-CHLORO-1,3-DIHYDRO-2H-INDOL-2-ONE - Introduction

4-Chloro-2-oxindole is an organic compound with the chemical formula C8H5ClNO. Its properties are as follows:

1. Appearance: colorless crystal or white powder.
2. Melting Point: about 118-122 ℃.
3. Boiling point: About 336 ℃.
4. Solubility: slightly soluble in water, soluble in organic solvents such as ethanol, ether, etc.

4-Chloro-2-oxindole is commonly used in organic synthesis and pharmaceutical research. It can be used as a bactericide, fungicide, antiviral drugs and alkaloid synthesis intermediates.

There are usually two ways to make 4-Chloro-2-oxindole:
1. Indole reacts with thionyl chloride to obtain 4-chloroindole, which is then oxidized in the presence of sodium hydroxide to generate 4-chloroo-2-oxindole.
2. Starting from indole, 4-Chloro-2-oxindole is prepared by chlorination or ozonation.

Note the following safety information when using and handling 4-Chloro-2-oxindole:
1. Avoid inhalation of dust and contact with skin, eyes and mucous membranes.
2. Should wear protective glasses, protective gloves and protective clothing in use.
3. Operate in a well-ventilated place and avoid inhaling its vapor.
4. In case of accidental contact, please rinse the skin with plenty of water and seek medical attention immediately.
