Cas no 31181-64-3 (5-Bromo-2-methyl-pyridine-1-oxide)

5-Bromo-2-methyl-pyridine-1-oxide is a heterocyclic compound featuring a pyridine core substituted with a bromo group at the 5-position and a methyl group at the 2-position, further oxidized to the N-oxide form. This structure enhances its reactivity, making it a valuable intermediate in organic synthesis, particularly in pharmaceutical and agrochemical applications. The presence of both bromine and the N-oxide moiety offers versatile reactivity for cross-coupling reactions, nucleophilic substitutions, and functional group transformations. Its well-defined crystalline form ensures consistent purity and handling stability, facilitating precise use in complex synthetic pathways. The compound is particularly useful in the development of bioactive molecules and fine chemicals.
