Names this molecule

CORRECTED 2026-08-14: this edge said the material was not held, and it is - as '16409-43-1' (CAS 16409-43-1). The gap was in the LOOKUP, not the catalogue: we store this molecule under its systematic or registry name, the edge was authored against the trade name, and nothing matched. Supplier catalogues published the CAS and PubChem confirmed it (CID 27866). Previously: A real molecule we do not hold as its own row - only 'Geranium oil (low rose oxide)', which names it without being it. The material that would realise

How the layers join

Origin

Rose oxide is a synthetic compound first identified in the essential oil of Rosa damascena but is now produced industrially via chemical synthesis. It exists as four stereoisomers, with the (−)-cis isomer being most relevant to perfumery due to its intense rosy-green character. Natural occurrence in rose oil is minimal, making synthetic production the standard for fragrance use.

Usage in Perfumery

Perfumers use rose oxide primarily in the heart of floral compositions to impart brightness and a modern, radiant lift to rose accords. It is often blended with other floral, green, and fruity notes to enhance freshness and create a sparkling effect. Its distinctive profile is also used to evoke litchi or to add complexity to contemporary floral and fruity fragrances.
