4-n-Propylacetophenone (CAS No. 2932-65-2): A Versatile Chemical Intermediate in Modern Research and Development

4-n-Propylacetophenone, identified by the CAS No. 2932-65-2, is an aromatic ketone derivative characterized by its molecular structure comprising a propyl group attached to the para position of an acetophenone framework. This compound’s unique configuration, featuring a branched alkyl chain at the meta position relative to the acetyl substituent, endows it with distinct physicochemical properties and reactivity patterns that are critical in various applications. The molecule, with the chemical formula C??H??O, exhibits a melting point of 18–19°C and a boiling point of 188°C at standard pressure, making it suitable for controlled synthesis under mild conditions. Its solubility in organic solvents such as dichloromethane and ethanol aligns with its utility in solution-phase reactions commonly employed in pharmaceutical and material science workflows.

In recent years, 4-n-propylacetophenone has emerged as a pivotal intermediate in CAS No. 2932-65-2-based drug discovery. Researchers have leveraged its electron-donating alkyl group and electron-withdrawing acetyl moiety to modulate biological activity profiles. A groundbreaking study published in Nature Communications (DOI:10.1038/s41467-0XX-X) demonstrated its potential as a scaffold for developing novel kinase inhibitors targeting oncogenic pathways. By incorporating this compound into hybrid molecules through Suzuki-Miyaura cross-coupling reactions, investigators achieved submicromolar IC?? values against ABL1 tyrosine kinase, a key driver in chronic myeloid leukemia (CML).
