Aldehyde C11 Undecylenic has an aldehydic and floral note with zesty and citrus undertones, reminiscent of orange and mandarin. It is very useful in floral and spicy composition and has a good fabric substantivity.
These share the same CAS number (112-45-8) — the same core molecule sold under different trade names. They're close to interchangeable, but purity and isomer ratio can cause subtle differences in strength and character, so treat them as near-identical rather than exactly the same.
