  • Applications

    The cis-3-Hexenal solution, CAS 6789-80-6, is widely applied as the key “green-leaf” flavor compound in food and fragrance industries, recreating fresh grass, cucumber and green-apple notes in chewing gums, beverages, salad dressings and fermented dairy products, while also serving as an essential ingredient in many perfumes, air fresheners and scented candles to impart a naturally refreshing nuance; in produce packaging and storage technologies it functions as a sensory freshness indicator that supports post-harvest research, and in molecular biology laboratories the solution is employed as an internal standard for quantifying lipoxygenase reactions, studying plant defense signaling, simulating flavor release in photoreactor models and calibrating odor sensitivity tests for professional sensory panels.
