Ethyl 3,5-dihydroxybenzoate丨CAS 4142-98-7

Ethyl 3,5-dihydroxybenzoate (CAS 4142-98-7) is an aromatic ester widely used as an intermediate in organic synthesis, pharmaceuticals, and cosmetic formulations. In medicinal chemistry, it serves as a building block for the synthesis of bioactive compounds, including anti-inflammatory, antioxidant, and antimicrobial agents. Its dihydroxy functional groups allow for further derivatization, such as esterification, etherification, or glycosylation, enabling the construction of complex molecules. Additionally, ethyl 3,5-dihydroxybenzoate is used in the synthesis of dyes, natural product analogs, and specialty chemicals, as well as in cosmetic formulations as a precursor for UV filters and antioxidant ingredients.

The benefits of ethyl 3,5-dihydroxybenzoate stem from its dual hydroxyl groups and ester functionality, which provide high chemical versatility. The hydroxyl groups enable hydrogen bonding and functionalization, while the ethyl ester enhances solubility and facilitates ester-based reactions. Its stability under standard storage conditions and solubility in common organic solvents make it convenient for multi-step synthesis and incorporation into various formulations. The compound's reactive and modifiable structure allows for the creation of derivatives with tailored bioactivity, solubility, and physicochemical properties, making it highly valuable in pharmaceutical, cosmetic, and fine chemical applications.
