Cas no 88491-61-6 (3-Bromopyridazine)

3-Bromopyridazine (CAS 1455-52-1) is a heterocyclic organic compound featuring a pyridazine ring substituted with a bromine atom at the 3-position. This compound serves as a versatile intermediate in organic synthesis, particularly in pharmaceutical and agrochemical applications. Its bromine moiety enables efficient cross-coupling reactions, such as Suzuki or Buchwald-Hartwig couplings, facilitating the construction of complex pyridazine derivatives. The electron-deficient nature of the pyridazine ring enhances reactivity in nucleophilic substitution reactions. 3-Bromopyridazine is valued for its stability under standard conditions and its compatibility with a range of reaction conditions, making it a reliable building block for researchers in medicinal chemistry and material science.
