Celery ketone is widely used in the fragrance and flavor industry due to its characteristic green, herbal, and slightly spicy aroma. It is a key ingredient in creating natural and fresh scents, often found in perfumes, colognes, and cosmetic products. Additionally, it is utilized in food flavorings to impart a celery-like taste to soups, sauces, and savory snacks. Its ability to enhance and mimic natural flavors makes it valuable in both synthetic and natural flavor formulations.
