Description

2-o-Methyl-1-O,3-O,4-o-Trimethyl-5-o-(2-O,3-O,4-O,6-o-Tetramethyl-β-D-Galactopyranosyl)-D-Fructopyranose CAS NO 55298-60-7 is a complex, high-purity methylated disaccharide derivative, specifically a methylated galactosyl-fructose. This compound is valued for its role as a key intermediate and reference standard in advanced carbohydrate chemistry research and synthesis. It is primarily required by pharmaceutical R&D laboratories, academic institutions, and specialty chemical manufacturers focused on glycoscience and novel carbohydrate-based molecules.

Application

• Pharmaceutical Intermediate: Serves as a critical building block in the synthesis of complex glycoconjugates, prodrugs, or novel therapeutic agents targeting carbohydrate-mediated biological processes.
• Biochemical Research: Used as a substrate, inhibitor, or standard in enzymatic studies, particularly those involving glycosyltransferases, glycosidases, or carbohydrate-binding proteins.
• Glycoscience Reference Standard: Acts as a high-purity analytical standard for method development and validation in chromatography (HPLC, GC) and mass spectrometry for carbohydrate analysis.
• Chemical Synthesis: Employed in organic synthesis to introduce specific, protected sugar moieties into larger molecular architectures, leveraging its multiple methyl protecting groups.
• Nutritional & Metabolic Studies: Potential use as a tracer or model compound in research investigating the digestion, absorption, or fermentation of modified dietary carbohydrates.

Quality Control

Our 2-o-Methyl-1-O,3-O,4-o-Trimethyl-5-o-(2-O,3-O,4-O,6-o-Tetramethyl-β-D-Galactopyranosyl)-D-Fructopyranose is produced under strict quality management systems. Each batch undergoes comprehensive analytical characterization using techniques including HPLC, NMR, and mass spectrometry to confirm identity and purity. Certificates of Analysis (COA) detailing batch-specific results are provided and available upon request to ensure traceability and compliance with your research or production requirements.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature, store in a cool, dry place, ideally under an inert atmosphere or with desiccant. Recommended long-term storage temperature is 2-8°C. Allow the container to reach room temperature before opening to prevent moisture condensation.
