Used as a flavoring agent in food and beverages for its sweet, creamy, vanilla-like aroma with enhanced stability. Commonly found in dairy products, confectionery, and baked goods where prolonged shelf life and heat resistance are required. Also utilized in perfumery to add warm, vanilla nuances with improved solubility in alcohol-based formulations. Its acetal structure provides better performance in low-pH environments compared to plain ethyl vanillin, making it suitable for flavored drinks and pharmaceutical syrups. Additionally, it is used in oral care products such as toothpaste and mouthwash to mask unpleasant odors and provide a pleasant flavor. Frequently used in e-liquids for electronic cigarettes due to its smooth flavor profile and compatibility with propylene glycol-based carriers.
