Isoeugenol
CAS Number: 97-54-1
Isoeugenol (CAS 97-54-1) is the isomeric form of eugenol with a sweeter, more floral, carnation-like fragrance compared to the spicier clove note of eugenol. It is produced by the isomerization of eugenol and used in perfumery for carnation and floral bouquet compositions, and as an intermediate in vanillin synthesis.
