Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors and other bioactive molecules. Its aldehyde and phenolic hydroxyl groups allow for further chemical modifications, such as condensation or coupling reactions, enabling the construction of complex drug-like structures. Commonly employed in medicinal chemistry for building blocks in central nervous system agents and anti-inflammatory compounds. Also utilized in research settings for designing novel piperazine-based therapeutics due to its favorable solubility and structural versatility.
