2-Isobutylthiazole is a synthetic organic compound used primarily as a flavoring agent and fragrance ingredient. It possesses a powerful, green, fruity odor reminiscent of tomato leaves, fresh vegetables, and galbanum. In the food industry, it is employed to enhance green and fruity notes in products such as tomato-based sauces, fruit beverages, pineapple flavors, and berry concoctions. In perfumery, it adds fresh, herbal, and vegetative accents to compositions, contributing to natural and ozonic scent profiles. Typically used in trace amounts due to its potent aroma.
