1-Bromo-2-ethylbenzene(CAS: 1973-22-4)

1-Bromo-2-ethylbenzene (CAS: 1973-22-4) is a crystalline compound with a molecular weight of approximately 183.04 g/mol. It has a low solubility in water (less than 1 g/L at 20°C) but is more soluble in organic solvents such as acetone and chloroform. Chemically, it is relatively stable but can undergo bromination reactions under appropriate conditions. It is insoluble in most inorganic solvents and has a melting point of about 25-27°C.

1-Bromo-2-ethylbenzene (CAS: 1973-22-4) is typically synthesized through a bromination reaction of 2-ethylbenzene with bromine. The reaction is conducted in the presence of a Lewis acid catalyst, such as iron(III) bromide, to facilitate the electrophilic aromatic substitution. The yield is usually around 70-80%, and the product can be isolated by simple distillation or recrystallization.

1-Bromo-2-ethylbenzene (CAS: 1973-22-4) is used in various industries, particularly in the synthesis of pharmaceuticals and organic chemicals. It serves as a starting material for the production of other brominated compounds, which are used in the pharmaceutical and plastic industries. Additionally, it can be used in the development of sensors and semiconductors due to its chemical properties.

When handling 1-Bromo-2-ethylbenzene (CAS: 1973-22-4), it is crucial to use personal protective equipment (PPE) such as gloves, safety goggles, and a lab coat. It should be handled in a well-ventilated area or a fume hood to avoid inhalation. Proper storage should be in a cool, dry place away from direct sunlight. In case of spill, immediately clean up with appropriate absorbents and follow the safety data sheet (SDS) for further instructions. Always ensure the SDS is readily available for reference.
