Trans-2-hexenal

Trans-2-hexenal (CAS 6728-26-3 ), also known by its FEMA 2560 designation, is an aldehyde-based aroma chemical used across flavor and fragrance manufacturing.

It delivers a fresh, green, apple-like character that perfumers and flavorists rely on to replicate natural fruit and botanical profiles in various industrial applications.

In food flavoring, it is used at low concentrations to build green apple, tomato, and fresh herb notes in beverages, confectionery, and savory products for global markets.

Fragrance houses incorporate it into fine perfumery and functional fragrance blends where fresh-cut green or leafy top notes are required for high-end consumer goods.

In personal care formulations, it contributes to shampoos, body washes, and skincare products targeting fresh fruit or botanical scent profiles for a natural experience.

It also appears in flavor reconstruction work, where matching the volatile profile of fresh produce demands precise inclusion of this compound to ensure sensory accuracy.

The material is supplied as a liquid, typically at high purity levels. Food-grade material conforming to FCC standards is the most commercially common specification available.

Buyers should confirm purity grade and isomeric composition when sourcing, as the trans-isomer content is critical to achieving the intended sensory profile in final products.
