Cyclopentanone

Cyclopentanone (CAS 120-92-3), also known commercially as adipic ketone and by FEMA 3910, is a cyclic ketone used as a flavoring and fragrance ingredient across food and personal care applications. Its characteristic mint-like, earthy, and slightly woody odor profile makes it a valued building block for flavor and fragrance houses sourcing aroma chemicals for diverse formulations.

In food flavoring, this compound is used at trace levels to contribute nuanced background notes in savory, dairy, and roasted flavor systems. Fragrance formulators incorporate it into personal care products. These applications include soaps, lotions, and hair care, where it adds depth to woody and green accords. It also functions as an intermediate in the synthesis of more complex aroma molecules.

This versatility makes it highly relevant to flavor and fragrance manufacturers operating their own chemical synthesis programs. The material is supplied as a clear liquid in drum and IBC quantities. These formats are suited to industrial flavor and fragrance production. It is available in flavor-grade quality meeting FEMA and relevant purity specifications for use in food-contact applications.

Buyers should confirm compliance documentation, including CoA and purity levels, when sourcing for regulated flavor applications. This ensures the material meets all necessary safety and quality standards.
