2-Bromo-5-chloronicotinaldehyde is a halogenated pyridine aldehyde featuring strategic bromo and chloro substituents at the 2- and 5-positions, respectively. This electron-deficient scaffold enables direct incorporation into cross-coupling reactions and serves as a key building block for bioactive heterocycles and functional materials.
2-Bromo-5-chloronicotinaldehyde serves as a versatile building block in synthetic organic chemistry, enabling the construction of functionalized heterocycles and pharmaceutical intermediates. Its reactivity is well-established in Suzuki-Miyaura and Buchwald-Hartwig coupling reactions, facilitated by the orthogonal handling of bromo and chloro substituents. The aldehyde group supports nucleophilic addition and oxime formation, offering efficient access to diverse scaffolds. Bench-stable and compatible with standard purification methods, it functions reliably in multi-step syntheses requiring selective transformation.
