Description

o-α-L-Arabinofuranosyl-(1-5)-o-α-L-Arabinofuranosyl-(1-5)-L-Arabinose is a defined, high-purity oligosaccharide derivative, specifically a linear trisaccharide composed of arabinose units. This compound serves as a critical reference standard and building block for advanced research and development in carbohydrate chemistry. It is essential for scientists and manufacturers in the pharmaceutical, nutraceutical, and life science research sectors who require precise, well-characterized molecules for analytical work, synthesis, and biological studies.

Application

• Pharmaceutical Reference Standard: Used for the identification, purity assessment, and quantification of arabinose-containing compounds in drug development and quality control (QC) laboratories.
• Biochemical Research: Serves as a substrate or inhibitor in enzymatic studies, particularly for arabinofuranosidases and other glycosyl hydrolases, to investigate carbohydrate metabolism.
• Glycoconjugate Synthesis: Acts as a key intermediate or precursor in the chemical and enzymatic synthesis of more complex glycans, glycoproteins, or glycolipids for therapeutic applications.
• Nutritional Science: Employed in research related to dietary fiber, prebiotics, and the analysis of arabinoxylan structures found in cereals and plant cell walls.
• Analytical Method Development: Utilized as a calibration standard in chromatographic (HPLC, HPAEC-PAD) and spectroscopic methods to develop and validate assays for carbohydrate analysis.
