2,4-Decadienoic acid

2,4-Decadienoic acid (CAS 30361-33-2) is a straight-chain unsaturated fatty acid used as a flavoring agent in food and fragrance applications. It contributes characteristic fatty, waxy, and citrus-like notes that replicate natural flavor profiles.

In food manufacturing, it is used to build or reinforce citrus, orange peel, and fatty top notes in beverages, confectionery, and savory flavor systems. Flavor houses incorporate it into reconstituted natural flavor blends where authentic fruit character is required.

It also finds use in fragrance compounding, where its waxy-green profile supports citrus and floral accords in fine fragrance and functional fragrance applications. This versatile ingredient is essential for creating complex aromatic structures.

As an acidulant with flavor-active properties, it can serve a dual role in formulations requiring both pH contribution and sensory impact. This makes it a valuable tool for product developers seeking multi-functional chemical components.

2,4-Decadienoic acid is typically supplied as a liquid or low-melting solid, depending on purity and storage conditions. It is available in flavor and fragrance grade suitable for use in food-contact applications.

Purity specifications are commonly at 98% or higher to ensure consistent performance in sensitive formulations. Packaging is generally offered in small quantities appropriate for specialty flavor ingredient sourcing and laboratory use.
