Descriptions

Comment (FraterWork)

Methyl Corylone (Donut DIketone) is a go-to chemical if you need to make a bready edible accord or gourmand scent. It creates immediate warmth at 0.1-0.3% in sweet accords. Pair with vanillin for bakery effects or lactones for milky caramel. Structure compositions with this material as a middle note bridge between fruity tops and woody bases. We also sell this at 10% in DPG for better workability across formulations. Use Methyl Corylone to elevate simple vanilla accords into sophisticated gourmand compositions that maintain character throughout dry-down. NOTE: The naming of this product can be confusing due to trade terminology, but the Ventos Safety Data Sheet (SDS) is accurate for what we’re selling. It lists the material as 3,4-Dimethyl-1,2-Cyclopentanedione (CAS 13494-06-9), correctly identifying its chemistry—a cyclopentane ring with two ketone groups at positions 1 and 2 and methyl groups at 3 and 4 (C₇H₁₀O₂). While we and Ventos use "Methyl Corylone" as a trade name for this compound, some in the fragrance industry might expect "Methyl Corylone" to refer to a different chemical, 2-hydroxy-3-methylcyclopent-2-en-1-one (CAS 80-71-7), which has a distinct structure and profile. aromachem Best Seller gourmand
