  • Applications

    Galactinol dihydrate (CAS 1217474-91-3) is primarily used as a biochemical intermediate and research reagent in plant carbohydrate metabolism, acting as a galactinol donor in the biosynthesis of raffinose family oligosaccharides (RFO) and as a substrate or standard in enzymatic assays for galactinol synthase and related enzymes; in carbohydrate chemistry, it serves as a building block for oligosaccharide synthesis and as an analytical reference material for methods such as HPLC or LC-MS; its applications are mainly in research, development, and analytical settings in plant carbohydrate biology, with usage governed by local regulations and formulation constraints.
