Methyl heptine carbonate

Methyl heptine carbonate (CAS 111-12-6), also known as Methyl 2-Octynoate and commercially as Folione, is a high-impact aroma chemical used in flavor and fragrance manufacturing. At trace concentrations, it delivers a sharp, violet-leaf and green character that defines its value to formulators working with fine fragrance and flavor systems.

In perfumery, it anchors green, leafy topnotes in fine fragrances, colognes, and functional fragrance products where naturalistic freshness is required for the final profile. Flavor houses use it at very low usage levels to replicate violet, orris, and green vegetable profiles in confectionery, beverage, and savory applications across the industry.

It carries FEMA 2729 status supporting its use in food-grade flavor formulations. In personal care, it appears in shampoos, body washes, and fabric care products. Its potency means small quantities contribute significantly to finished formulations, which remains a key consideration for industrial cost-in-use calculations and efficiency.

The chemical is supplied as a clear liquid, typically at high purity levels suited to fragrance and flavor end uses. It is available in fragrance-grade and food-grade specifications. Packaging ranges from small quantities for laboratory and development use up to bulk drum supply for industrial fragrance production and large scale manufacturing needs.
