FAQ

What are the physical and chemical properties of 1,2-Dichloro-3-methylbenzene (CAS: 32768-54-0)?

1,2-Dichloro-3-methylbenzene is a crystalline solid with a molecular weight of approximately 172.02 g/mol. It has a low solubility in water but is more soluble in organic solvents like ethanol and acetone. Chemically, it is relatively stable but can undergo electrophilic aromatic substitution reactions. It has a density of about 1.32 g/cm³ and a melting point of around 41-43°C.

How is 1,2-Dichloro-3-methylbenzene (CAS: 32768-54-0) typically synthesized?

1,2-Dichloro-3-methylbenzene can be synthesized through the chlorination of 3-methylbenzene in the presence of a Lewis acid catalyst, such as aluminum chloride. The chlorination typically occurs at elevated temperatures, with good yields and high selectivity for the 1,2-dichloro position.

What industries use 1,2-Dichloro-3-methylbenzene (CAS: 32768-54-0)?

1,2-Dichloro-3-methylbenzene is primarily used in the pharmaceutical industry for the synthesis of various intermediates and active pharmaceutical ingredients. It is also used in the polymer industry as a monomer or comonomer, and in the electronics sector for the production of semiconductors and sensors due to its aromatic nature.

What precautions should be taken when handling 1,2-Dichloro-3-methylbenzene (CAS: 32768-54-0)?

When handling 1,2-Dichloro-3-methylbenzene, it is essential to wear appropriate personal protective equipment (PPE) such as gloves, safety goggles, and a lab coat. Work should be conducted in a well-ventilated area or fume hood to minimize exposure. Proper spill cleanup procedures should be followed, and the Substance Safety Data Sheet (SDS) should be consulted for detailed safety information and emergency procedures.
