Butanedione

Butanedione ( CAS 431-03-8 ), commercially recognized as diacetyl, is a diketone compound used as a flavoring agent and functional ingredient across food, fragrance, and industrial applications. Its characteristic buttery aroma profile makes it a reference material in flavor development and a target compound in quality control testing for various manufacturing sectors. In food and beverage manufacturing, diacetyl ( FEMA 2370 ) is used to impart butter, cream, and caramel notes in margarines, dairy analogs, and microwave popcorn coatings. Flavor houses use it as a building block in complex flavor compositions where low-level dosing achieves high aromatic impact in confectionery products and baked goods. In personal care, it contributes to fragrance blends targeting warm, gourmand, or dairy-inspired scent profiles. Its reactive diketone functionality also supports cross-linking applications. This material is utilized in certain polymer and resin curing systems. Butanedione is supplied as a liquid, typically in drum and IBC quantities for industrial buyers. Food-grade material is available to FCC specification, which is the standard grade for flavor and food manufacturing procurement and regulatory compliance. Technical-grade supply is also available for non-food industrial uses including fragrance compounding and chemical synthesis for specialized laboratory and production needs.
