Description

1,6-Anhydro-3,4-o-Isopropylidene-2-o-(2,3,4,6-Tetra-o-Acetyl-β-D-Galactopyranosyl)-β-D-Galactopyranose CAS NO 127527-87-1 is a sophisticated, fully protected disaccharide derivative, serving as a critical advanced intermediate in synthetic carbohydrate chemistry. Its value lies in providing a reactive scaffold for the precise construction of complex oligosaccharides and glycoconjugates, enabling research and development in biologically active compounds. This high-purity building block is essential for pharmaceutical R&D teams, diagnostic developers, and academic researchers focused on glycoscience, glycomics, and the synthesis of novel therapeutic agents.

Application

• Pharmaceutical Intermediate: Key building block for the synthesis of complex carbohydrate-based active pharmaceutical ingredients (APIs) and prodrugs.
• Glycoconjugate Synthesis: Used in the preparation of glycoproteins, glycolipids, and neoglycoconjugates for immunological and therapeutic studies.
• Oligosaccharide Assembly: Serves as a crucial, selectively protected donor or acceptor molecule in automated and solution-phase oligosaccharide synthesis.
• Diagnostic Reagent Development: Employed in creating specific carbohydrate probes and antigens for diagnostic assays and biosensors.
• Glycomics Research: A valuable tool for studying carbohydrate-protein interactions, enzyme mechanisms, and metabolic pathways.
• Chemical Biology Probes: Foundation for synthesizing labeled or tagged sugars to investigate biological processes at the molecular level.

Quality Control

This high-value synthetic intermediate is produced under strict quality control protocols to ensure batch-to-batch consistency and high chemical purity. Our standard grade typically meets a purity specification of ≥95% (by HPLC), with comprehensive identity confirmation via spectroscopic methods. Certificates of Analysis (COA) detailing purity, identity (IR, NMR), and specific impurity profiles are provided with each shipment to support your critical R&D and cGMP-aligned workflows.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This compound is hygroscopic (moisture-sensitive) and should be handled under anhydrous conditions to maintain stability and purity. For long-term storage, consider desiccation.
