5-Bromosalicylic Acid丨CAS 89-55-4

5-Bromosalicylic acid is an important aromatic brominated compound widely used as an intermediate in organic synthesis, pharmaceutical research, and fine chemical production. It is commonly employed in the preparation of dyes, pigments, and UV-absorbing materials due to its functionalized phenolic and carboxylic groups. In medicinal chemistry, 5-bromosalicylic acid serves as a building block for synthesizing bioactive molecules, enzyme inhibitors, and heterocyclic compounds. Its bromine substituent facilitates selective cross-coupling, substitution, and functionalization reactions, making it useful for multi-step synthetic pathways. Additionally, it is applied in analytical chemistry and materials science as a precursor for developing fluorescent probes and functionalized polymers.

5-Bromosalicylic acid offers several advantages due to its dual functional groups and reactive bromine atom. The phenolic hydroxyl and carboxyl groups enable hydrogen bonding, chelation, and esterification reactions, while the bromine atom provides versatility for nucleophilic substitution or palladium-catalyzed coupling reactions. This combination of reactivity and stability allows for efficient synthesis of complex molecules with high yields. The compound is chemically stable under normal storage conditions and soluble in common organic solvents, supporting reproducible reactions and scalable production. Its well-defined structure and functional diversity make it a reliable intermediate for both laboratory and industrial applications.
