3-BROMO-5-CHLOROBENZO[B]THIOPHENE - Introduction
3-Bromo-5-chlorobenzo [B] thiophene is an organic compound whose chemical formula is C10H5BrClS. The following is a description of its nature, use, preparation and safety information:
Nature:
-Appearance: 3-Bromo-5-chorobenzo [B] thiophene as light yellow crystals
-Melting point: approximately 60-65°C
-boiling point: data does not exist
-Solubility: Soluble in organic solvents (such as ether, dichloromethane, etc.), insoluble in water
Use:
3-Bromo-5-chlorobenzzo [B] thiophene are commonly used as intermediates for organic photovoltaic materials, organic light emitting diode (OLED) materials, and organic electroluminescent (OEL) materials.
Preparation Method:
3-Bromo-5-chlorobenzzo [B] thiophene can be prepared by a three-step reaction:
1. First, spiro thiophene ring on benzene ring to obtain 2-bromo-4-chlorophenylthiophene
2. Then, introduce another bromine atom on 2-bromo-4-chlorophenylthiophene to obtain 3,4-dibromo-2-chlorophenylthiophene
3. Finally, a reduction reaction (using ferrous powder) occurred on 3,4-dibromo-2-chlorophenylthiophene to obtain the final 3-Bromo-5-chlorobenzo [B] thiophene.
Safety Information:
3-Bromo-5-chlorobenzzo [B] thiophene have not been reported to be toxic or hazardous under normal conditions of use. However, as a chemical, the following safety measures need to be taken before use:
-Wear appropriate personal protective equipment such as lab gloves, safety glasses and protective jackets when using chemicals in the laboratory.
-avoid contact with skin and eyes, if accidentally contact, please rinse with plenty of water, and timely medical treatment.
-When using and storing, it should be placed in a sealed container, away from fire and heat sources.
-Disposal of waste items must comply with local regulations and standards.
