Cas no 99032-67-4 ((2r)-1-bromo-2-methylbutane)

(2R)-1-Bromo-2-methylbutane is a chiral alkyl halide with the molecular formula C?H??Br, characterized by its stereocenter at the second carbon. This compound is commonly employed as an intermediate in organic synthesis, particularly in stereoselective reactions such as nucleophilic substitutions and Grignard reagent formations. Its defined (R)-configuration ensures precise control over enantioselective outcomes, making it valuable in pharmaceutical and fine chemical applications. The bromine substituent enhances reactivity in cross-coupling and alkylation processes. The branched methyl group influences steric and electronic properties, offering selectivity advantages. Suitable for inert atmosphere handling, it is typically stored under refrigeration to maintain stability. Purity and stereochemical integrity are critical for reproducible results.
