  • Applications

    Methyl jasmonate (CAS 39924-52-2) is a naturally occurring phytohormone whose versatile applications span agriculture, biotechnology, cosmetics and medical research: in the field it is sprayed or used as a post-harvest dip on fruits and vegetables to switch on endogenous defense pathways, thereby enhancing resistance to insects and pathogens, lowering fungal decay and slowing softening so shelf life is extended; in plant tissue or hairy-root cultures it serves as a powerful elicitor that boosts the biosynthesis of high-value secondary metabolites such as alkaloids, terpenoids and flavonoids, raising the pharmacological quality of herbal raw materials; additionally, methyl jasmonate contributes a delicate jasmine-like note to fine fragrances, is explored as an antiproliferative agent in preclinical cancer studies, and remains an indispensable molecular tool for probing stress-signal transduction in plants.
