4-Methyl-1-naphthaldehyde is an organic compound found in cigarette smoke and has been identified in the microenvironment surrounding pancreatic cancer cells. it is a precursor to naphthalene, a carcinogen, which undergoes a reaction with ammonium nitrate to form nitrosoamines. Notably, 4-Methyl-1-naphthaldehyde exhibits the ability to inhibit the growth of tumor cells by binding to topoisomerase and hindering DNA synthesis. This molecule′s inhibitory properties on tumor cells may be attributed to its ability to react with amines. Additionally, 4-Methyl-1-naphthaldehyde is a reagent used in the preparation and immunosuppressive activity of lactones through ring-closing metathesis of alkadienes.
