2-heptanone

CAS: 110-43-0

Overview

2-Heptanone (CAS 110-43-0 ), also known as methyl amyl ketone or MAK, is a medium-chain ketone solvent used across industrial, cosmetic, and food applications. It delivers strong solvency for resins and coatings while contributing a fruity, banana-like character valued in flavor and fragrance work.

In coatings and industrial cleaning, this compound dissolves nitrocellulose, acrylics, and vinyl resins, offering a slower evaporation rate that improves flow and leveling in spray-applied finishes. Metalworking and lubricant formulators use it as a carrier solvent to aid in the deposition of active compounds onto metal surfaces.

In personal care, it functions as a solvent and fragrance ingredient in nail care products, hair preparations, and skin formulations. Food manufacturers use it as a flavoring agent under FEMA 2544 to impart fruity, cheese-like, or banana notes in baked goods, dairy products, and beverages.

The product is supplied as a clear liquid in drums and IBC totes for bulk industrial procurement. It is available in technical grade for solvent and metalworking applications and in food/flavor grade meeting FEMA and FCC specifications for use in consumable products.
