Widely used in the pharmaceutical and biotechnology industries, this compound plays a key role in the development of antiviral drugs, particularly in treatments targeting influenza and other viruses that interact with sialic acid receptors. It serves as a critical building block in the synthesis of glycoconjugates and glycoproteins, which are essential for cell signaling and immune response modulation. Commonly used in research on glycosylation processes, it supports the study of neurological development and cancer biomarkers. Also found in some infant formulas and dietary supplements, it contributes to cognitive development and immune system support. Its derivatives are explored in drug delivery systems for targeted therapies, especially in oncology and neurodegenerative diseases.
