Ethyl 3,5-Dihydroxybenzoate is widely used in the pharmaceutical industry as an intermediate in the synthesis of various active pharmaceutical ingredients (APIs). Its structure makes it valuable for developing compounds with potential antioxidant, anti-inflammatory, and antimicrobial properties. In cosmetic formulations, it serves as a stabilizer and preservative, helping to extend the shelf life of products by preventing microbial growth. Additionally, it is utilized in organic synthesis to create more complex molecules for research and industrial applications. Its dual hydroxyl groups make it a versatile building block in chemical reactions, particularly in the production of polyphenols and other bioactive compounds.
