Methyl Octyne Carbonate is widely used in floral notes. It produces the powerful yet subtle note of violet leaves with a fruity-vegetable, cucumber undertone.
These share the same CAS number (111-80-8) — 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.
