Cas no 938458-80-1 (5-Bromo-2-ethylbenzodoxazole)
5-Bromo-2-ethylbenzodoxazole is a heterocyclic compound featuring a benzodoxazole core substituted with a bromine atom at the 5-position and an ethyl group at the 2-position. This structure imparts unique electronic and steric properties, making it a valuable intermediate in organic synthesis and pharmaceutical research. The bromine substituent enhances reactivity for cross-coupling reactions, such as Suzuki or Buchwald-Hartwig couplings, while the ethyl group contributes to solubility and stability. Its well-defined molecular framework is advantageous for developing ligands, catalysts, or bioactive molecules. The compound is typically handled under inert conditions due to its sensitivity to moisture and light, ensuring consistent performance in synthetic applications.
