2-Bromo-1-phenylpropane, also known as α-bromo-α-phenylpropane, is an organic compound with the chemical formula C9H11Br. It belongs to the family of haloalkanes and is specifically classified as a bromoalkane due to the presence of a bromine atom (Br) attached to a carbon chain.

The molecular structure of 2-Bromo-1-phenylpropane consists of a phenyl group (C6H5-) attached to a propyl chain (C3H7-) with a bromine atom (Br) bonded at the second position of the propyl chain.

The compound appears as a colorless to pale yellow liquid at room temperature, and it has a distinct aromatic odor due to the presence of the phenyl group. It is sparingly soluble in water but is soluble in various organic solvents like ethanol, acetone, and diethyl ether.

2-Bromo-1-phenylpropane is mainly used as a reactive intermediate in organic synthesis and the production of pharmaceuticals and agrochemicals. It is a valuable building block in the synthesis of various organic compounds due to its reactivity. Some common reactions involving this compound include nucleophilic substitution, Grignard reactions, and Suzuki coupling reactions.

As with any brominated compound, 2-Bromo-1-phenylpropane should be handled with care, and proper safety precautions should be followed, including proper ventilation and the use of protective equipment, as bromoalkanes can pose health hazards and can be irritating to the skin, eyes, and respiratory system.


As of my knowledge cutoff in September 2021, there is limited specific information available about the uses of 2-Bromo-1-phenylpropane. However, based on its chemical structure as a bromoalkane, it is likely used as a reactive intermediate in organic synthesis and various chemical reactions. Here are some potential uses:

1. Organic Synthesis: 2-Bromo-1-phenylpropane can serve as a building block in the synthesis of various organic compounds. It may participate in reactions such as nucleophilic substitution, Grignard reactions, and other carbon-carbon bond-forming reactions, which are common in organic synthesis.

2. Pharmaceutical Intermediates: Some bromoalkanes are utilized in the pharmaceutical industry as intermediates in the synthesis of active pharmaceutical ingredients (APIs). 2-Bromo-1-phenylpropane could potentially find applications in this context.

3. Agrochemicals: Bromoalkanes can also be used as intermediates in the production of agrochemicals, such as pesticides and herbicides.

4. Chemical Research: Chemical researchers may use 2-Bromo-1-phenylpropane as a reagent or precursor in laboratory experiments to explore new chemical reactions and develop novel compounds.

5. Coupling Reactions: It might be involved in coupling reactions, such as Suzuki coupling or Heck coupling, to form complex organic molecules.

Please note that the actual uses of 2-Bromo-1-phenylpropane may vary, and its applications could be more specific and specialized. The information provided here is general and based on the likely reactivity of bromoalkanes in organic chemistry. For specific applications or uses beyond this, up-to-date literature or information from chemical suppliers would be needed. Also, it is important to remember that chemical substances should always be handled with proper safety precautions, and any use of 2-Bromo-1-phenylpropane should be in compliance with relevant regulations and guidelines.
