(R)-2-Amino-2-(3-bromophenyl)ethanol, with CAS number 209963-04-2, is a chiral amino alcohol derivative featuring a 3-bromophenyl substituent. This compound serves as a crucial chiral building block in pharmaceutical synthesis. Its structure combines a primary amine and a primary alcohol functional group, making it a versatile intermediate for constructing more complex molecules. The primary application of this compound is as a key chiral intermediate in the synthesis of active pharmaceutical ingredients (APIs). It is notably used in the preparation of adrenergic receptor agonists and other bioactive molecules where the (R)-configuration is essential for biological activity. The bromine atom on the phenyl ring provides a handle for further functionalization via cross-coupling reactions, such as Suzuki or Buchwald-Hartwig couplings, allowing for the introduction of diverse substituents. As a chiral synthon, it is valuable for introducing stereochemistry into target drug molecules. Handling requires standard precautions for amino alcohols and bromoarenes, including the use of personal protective equipment.
