Methyl 2-bromo-2-methylpropanoate(CAS: 23426-63-3)

Methyl 2-bromo-2-methylpropanoate is a colorless to slightly yellow liquid at room temperature. It has a molecular weight of approximately 189.04 g/mol. The compound is poorly soluble in water but miscible with organic solvents. It is moderately reactive towards nucleophiles and can undergo nucleophilic substitution reactions. Its density is around 1.23 g/cm³.

Methyl 2-bromo-2-methylpropanoate can be synthesized by bromination of 2-methylbutan-2-ol using N-bromosuccinimide (NBS) in the presence of a radical initiator like benzoyl peroxide. The reaction is typically carried out in an inert solvent like dichloromethane or toluene. The selectivity and yield of the reaction are influenced by the reaction conditions, such as temperature and solvent choice.

Methyl 2-bromo-2-methylpropanoate is primarily used in the pharmaceutical industry as an intermediate for the synthesis of various drugs. It also finds applications in the polymer industry, where it serves as a monomer or a functionalizing agent. Additionally, it can be used in the development of sensors and semiconductors.

When handling Methyl 2-bromo-2-methylpropanoate, it is important to wear appropriate personal protective equipment (PPE), including gloves, goggles, and a lab coat. Work should be conducted in a well-ventilated area or a fume hood to minimize exposure to bromine vapor. Spills should be cleaned up using appropriate safety measures, and the Material Safety Data Sheet (MSDS) should be consulted for specific handling and disposal instructions.
