Anethole is widely used in the flavor and fragrance industry due to its sweet, licorice-like aroma. It is a key component in the formulation of food flavorings, particularly in confectionery, baked goods, and alcoholic beverages such as ouzo, absinthe, and pastis. Its pleasant taste and odor also make it suitable for use in oral hygiene products like toothpaste and mouthwash.

In the pharmaceutical sector, anethole exhibits antimicrobial and anti-inflammatory properties, making it useful in topical preparations and herbal remedies. It is also investigated for its potential estrogenic and anticancer activities, supporting its use in traditional medicine.

Additionally, anethole serves as a precursor in the synthesis of other chemicals, including certain polymers and specialty compounds. Its natural occurrence in essential oils like anise and fennel oil enhances its appeal in natural and organic product formulations.
