α-Irone or Methyl alpha-iononeis a natural aromatic ketone known for its rich, elegant orris-like scent for fragrance needs. Found in trace amounts in iris root (orris butter), α-Irone or simply called as Irone is used as a key component in violet, floral, and woody fragrances. Due to its high cost in natural form, it is often synthesized for fine fragrance formulations and luxury perfumery. High-value orris-type ketone for premium perfumery, offering longevity and soft floral depth. It builds complexity in violet, woody, and powdery fragrance profiles and is deeply preferred for its excellent blending characteristics in luxury compositions. It is also known as 6-Methyl ionone.
