FAQ

What are the physical and chemical properties of 1,8-Dibromooctane (CAS: 4549-32-0)?

1,8-Dibromooctane (CAS: 4549-32-0) is a colorless liquid with a molecular weight of 262.09 g/mol. It is slightly soluble in water but miscible with most organic solvents. Chemically, it is reactive towards nucleophiles due to the bromine substituents and can undergo substitution reactions. It has a distinctive smell characteristic of bromine compounds.

How is 1,8-Dibromooctane (CAS: 4549-32-0) typically synthesized?

1,8-Dibromooctane is typically synthesized through the reaction of 1-octene with bromine in the presence of a Lewis acid catalyst, such as aluminum bromide. This process involves electrophilic addition of bromine to the double bond of 1-octene, followed by elimination of hydrogen bromide to form 1,8-dibromooctane.

What industries use 1,8-Dibromooctane (CAS: 4549-32-0)?

1,8-Dibromooctane (CAS: 4549-32-0) is used in the pharmaceutical industry as a precursor for the synthesis of brominated compounds with specific biological activities, in the semiconductor industry for the production of certain organic materials, and in the polymer industry for making brominated polymers with improved flame retardant properties.

What precautions should be taken when handling 1,8-Dibromooctane (CAS: 4549-32-0)?

When handling 1,8-Dibromooctane (CAS: 4549-32-0), appropriate personal protective equipment (PPE) such as gloves, goggles, and a lab coat should be worn. It should be stored in a well-ventilated area and handled in a fume hood to minimize exposure. Spills should be cleaned up using appropriate spill response protocols, and the Material Safety Data Sheet (MSDS) should be consulted for detailed safety information.
