Methyl dihydrojasmonate HC (CAS 24851-98-7) — Floral Heart Note Fragrance Ingredient
Methyl dihydrojasmonate HC
CAS 24851-98-7
What Is Methyl dihydrojasmonate HC?
Methyl dihydrojasmonate is a synthetic floral ingredient found in many perfumes and scented products. It mimics the sweet, delicate aroma of jasmine flowers but with greater stability. This versatile molecule helps create long-lasting floral bouquets in everything from luxury perfumes to laundry detergents.
Safety Profile
GENERALLY SAFEWhat Does Methyl dihydrojasmonate HC Smell Like?
Methyl dihydrojasmonate opens with a crisp, slightly fruity floralcy reminiscent of jasmine petals dipped in pear nectar. As it evolves, the heart reveals a velvety, creamy richness with nuances of green tea leaves and a whisper of citrus peel. The dry-down is remarkably persistent, leaving a soft musky-floral trail that blends seamlessly with woody bases. Compared to natural jasmine absolutes, it’s less indolic and more transparent – like viewing a jasmine bouquet through frosted glass.
Scent Profile
In Famous Fragrances
Fragrance associations may not reflect actual formulations.
Used alongside natural jasmine to create the iconic lily-of-the-valley accord, providing a clean, radiant floralcy that lasts throughout the wear.
Forms the crystalline floral heart, blending with quince and grapefruit to create a modern, airy interpretation of spring flowers.
Provides the subtle floral underpinning to the citrus top notes, acting as a bridge to the woody-musky base.
Used extensively to amplify and extend the jasmine absolute, creating the perfume’s signature golden floral cascade.

Chemistry, Properties & Perfumer Guide
The Chemistry
Methyl dihydrojasmonate belongs to the jasmonate family of aroma compounds, structurally related to jasmine lactone. It’s produced synthetically through cyclization and esterification reactions, typically starting from cyclopentanol derivatives. The molecule exists as a racemic mixture in commercial products, though enantiopure forms show slightly different olfactory profiles. Its stability under various pH conditions makes it particularly valuable in functional fragrances.

Sustainability
As a synthetic ingredient, methyl dihydrojasmonate provides a sustainable alternative to natural jasmine extracts, which require extensive land use and labor-intensive harvesting. Modern production methods have significantly reduced environmental impact through improved catalytic efficiency and reduced solvent use. The material’s stability also reduces fragrance loss during product use, potentially lowering overall environmental load.
