Used primarily in the fragrance and flavor industry, angelic acid contributes to the synthesis of esters that impart fruity and floral notes in perfumes and cosmetics. It is also involved in the preparation of pharmaceutical intermediates, where it serves as a building block for certain bioactive compounds. Due to its natural occurrence in some plants, it finds use in the development of natural product-based formulations and aroma chemicals. Additionally, angelic acid derivatives are studied for their potential antimicrobial and anti-inflammatory properties, supporting research in medicinal chemistry.
