Description
Hexanal (CAS 66-25-1) is a six-carbon aliphatic aldehyde commercially known as hexaldehyde, n-Hexanal, and FEMA 2557. It does not carry an E-code designation. It occurs naturally in many plant-derived oils and is produced synthetically for industrial supply.
In food flavoring, hexanal delivers a fresh, green, grass-like note at low concentrations, making it a functional building block in fruit and vegetable flavor systems. In personal care formulations, it serves as a fragrance intermediate where its aldehydic character contributes to fresh, clean top notes in finished compositions.
Hexanal is supplied as a liquid and is available in flavor-grade quality conforming to FCC specifications. It falls under REACH regulation and is classified under HS code 29121900 for customs purposes. Procurement quantities typically range from small laboratory volumes to bulk industrial packaging depending on supplier capability.
