A powerful lemon-citrus aroma chemical with a fresh, slightly fatty-aldehydic top and a green, rindy undertone. Softer and less sharp than citral itself, with better stability, giving a rounded lemon-verbena effect that lifts citrus and cologne accords.AI · claude-opus-4-7

Colorless liquid.
Insoluble in water, soluble in alcohol and oils.
Powerful and diffusive, waxy-fatty-floral odor, yet refreshing and natural odor. It is much sweeter and less lemony than Citral, and it has more of the natural Citral-Nerol character as for instance observed in Lemon Petitgrain oil, or in terpeneless Lemon oil.
The taste of this material is floral-lemony, but somewhat bitter in concentrations above 20 ppm.
The title aldehyde could be used in fresh-floral compositions, such as Muguet, Lily, Ylang, and in many floral Citrus compositions, in 'spring bouquet' fragrance types, etc. It adds a pleasant freshness to Hydroxy-citronellal, and blends excellently with many carbinols.
Produced via Iso-Butylheptenone and Grignard reaction with Ethoxy acetylene to an Acetylenic compound which is reduced and treated with weak hydrochloric acid to yield the subject aldehyde.
