Description

Heptanoic acid ( CAS 111-14-8 ), also known as oenanthic acid, is a seven-carbon saturated fatty acid used as a chemical intermediate, flavoring agent, and functional ingredient across food, fragrance, and pharmaceutical manufacturing. Its FEMA 3348 designation supports regulated use in flavor applications. Buyers source it primarily as a building block for esters, salts, and specialty derivatives for various industrial applications. In flavor and fragrance formulation, heptanoic acid contributes fruity, rancid, and waxy top notes. It serves as a precursor to heptyl esters used in artificial fruit flavors and aromatic compounds. Personal care manufacturers incorporate it into emulsifier and surfactant synthesis, where its chain length influences HLB balance in finished formulations. This ensures stability in complex cosmetic mixtures. Pharmaceutical producers use it as an intermediate in the synthesis of active ingredients and excipient esters requiring a C7 acid backbone. It also functions as a pH regulator and preservative component. The material is utilized in select industrial and cosmetic systems where medium-chain fatty acid activity is required. Heptanoic acid is supplied as a clear to pale yellow liquid for commercial use. Standard commercial grades include technical and food/flavor-grade material, with the latter meeting purity requirements aligned with FEMA-listed use. Packaging typically ranges from drums to IBC containers. Bulk procurement options are available to meet the needs of large-scale manufacturing. The product maintains high stability when stored under appropriate conditions in industrial settings. Contact us for supply of Heptanoic acid Request Quote
