2,4-Dienals (such as 2,4-decadienal, CAS 25152-84-5, or related isomers) are powerful fatty-aldehydic materials with a characteristic fried-fat, citrus-peel and green-pear character. In dilution they read as oily-citrus and slightly waxy, with a distinct deep-fried or chicken-skin nuance at higher levels. They add lift and a natural, juicy fattiness to citrus and fruity accords.AI · claude-opus-4-7
