Geranyl bromide is an organic halide used primarily as a building block in synthetic fragrances, flavor compounds, and pharmaceutical intermediates due to its geraniol-derived structure. It serves as a key reagent in organic synthesis as an allylic alkylating agent, transferring the geranyl group to nucleophiles such as phenols, amines, enolates and thiols, with bromide as the leaving group, for example in the O-geranylation of umbelliferone to give auraptene (7-geranyloxycoumarin). This chemical has a CAS number of 6138-90-5, with the molecular formula C10H17Br and a molecular weight of 217.15 g/mol. It must be stored between 2 to 8°C and carries a signal word of "Warning" for its moderate hazard profile. Molekula supplies Geranyl bromide from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
