Galactose (CAS 59-23-4) is a monosaccharide hexose sugar that appears as a white crystalline powder, is known commercially as brain sugar, and serves as a carbon source in cell culture and microbial fermentation, a precursor for galacto-oligosaccharides, and a pharmaceutical excipient and diagnostic reagent. We offer high-purity D-Galactose in crystalline form, optimized for superior water solubility and industrial process stability. It is a key precursor for Galacto-oligosaccharides (GOS) , driving innovation in functional nutrition and prebiotic development. Our Pharma Grade Galactose adheres to global purity standards, making it an ideal pharmaceutical excipient and diagnostic reagent. It provides a specialized bio-active energy source particularly suited for advanced infant formulas and clinical nutrition.

Galactose
Applications
- Cell Culture Media Optimization: Acts as a specialized carbon source to improve the glycosylation profiles and yields of recombinant proteins in bioprocessing.
- Pharmaceutical Formulation: Utilized as a high-purity excipient and carrier in drug delivery systems and as a clinical reagent for metabolic diagnostic testing.
- Functional Food Production: Serves as the primary building block for prebiotic synthesis, supporting the development of healthy gut microbiota in specialized dietary products.
Safety & Risks
Galactose is not classified as hazardous; however, avoid generating combustible dust concentrations. Operators should wear safety goggles, protective gloves, and a dust mask (N95) during bulk handling to ensure respiratory safety.
