1-Bromo-2,3-dichlorobenzene(CAS: 56961-77-4)

1-Bromo-2,3-dichlorobenzene is a white crystalline solid with a molecular weight of approximately 241.54 g/mol. It is poorly soluble in water but soluble in organic solvents like ether and chloroform. The compound is moderately reactive towards nucleophiles and electrophiles. It has a melting point of around 58-59°C and a boiling point of about 225-227°C under atmospheric pressure.

1-Bromo-2,3-dichlorobenzene can be synthesized by bromination of 2,3-dichlorobenzene using a brominating agent like N-bromosuccinimide (NBS) in the presence of a peroxide initiator. This reaction is typically carried out in an inert atmosphere to prevent side reactions. The yield is generally around 80-90%, and the reaction is highly selective for the bromination at the meta position.

1-Bromo-2,3-dichlorobenzene is used in the pharmaceutical industry for the synthesis of certain drugs and intermediates. It is also utilized in the production of dyes, pesticides, and as a precursor in the manufacturing of polymers and sensors. The compound’s unique chemical structure makes it valuable in various applications requiring specific functional groups.

When handling 1-Bromo-2,3-dichlorobenzene, it is essential to wear appropriate personal protective equipment (PPE), including gloves, goggles, and a lab coat. The compound should be stored in a cool, dry place away from direct sunlight and heat sources. In case of a spill, avoid direct contact and use appropriate containment materials to prevent dispersion. Always consult the Safety Data Sheet (SDS) for detailed handling and emergency procedures.
