Description

D-Erythro-D-Galacto-Octitol is a high-purity, eight-carbon sugar alcohol (alditol) derived from galactose. This specialized polyol serves as a critical chiral building block and reference standard in advanced biochemical research and pharmaceutical development. It is essential for researchers and manufacturers in the life sciences, particularly for studying carbohydrate metabolism, enzyme mechanisms, and as a precursor in the synthesis of complex glycoconjugates and novel therapeutics.

Application

• Biochemical Research: Used as a chiral intermediate and standard in the study of carbohydrate-active enzymes, metabolic pathways, and glycosylation processes.
• Pharmaceutical Development: Serves as a key starting material or reference compound in the synthesis of glycomimetics, drug candidates, and diagnostic agents.
• Nutritional Science: Investigated for its potential metabolic properties and applications in specialized nutritional formulations.
• Cosmetic Science: Explored as a humectant or moisturizing agent in high-end skincare products due to its polyol structure.
• Analytical Standards: Employed as a high-purity certified reference material (CRM) for calibration in chromatographic (HPLC, GC) and spectroscopic analyses.
• Glycobiology: Fundamental tool for probing lectin-carbohydrate interactions and cell surface recognition events.
