Description

Methyl-4,6-Di-o-(4-Methoxybenzylidene)-2,3-Di-o-Benzyl-α-D-Mannopyranoside CAS NO 211231-57-1 is a sophisticated, multi-protected carbohydrate derivative, specifically a mannopyranoside, designed for advanced synthetic chemistry applications. This compound is a critical high-purity building block for the synthesis of complex oligosaccharides, glycoconjugates, and biologically active molecules. It is essential for R&D and production teams in pharmaceutical development, particularly in carbohydrate-based drug discovery and vaccine research.

Application

• Glycochemistry & Oligosaccharide Synthesis: A key protected intermediate for the controlled, stepwise construction of complex mannose-containing oligosaccharides and glycans.
• Pharmaceutical Intermediate: Serves as a crucial precursor in the development of carbohydrate-based active pharmaceutical ingredients (APIs), prodrugs, and diagnostic agents.
• Glycobiology Research: Used in academic and industrial research to study carbohydrate-protein interactions, enzymatic processes, and cell signaling pathways.
• Vaccine Adjuvant Development: Employed in the synthesis of synthetic carbohydrate antigens or adjuvants that mimic natural polysaccharide structures.
• Chemical Biology Probes: Acts as a starting material for creating labeled or tagged carbohydrate probes to study biological systems.
• Process Chemistry & Scale-up: Suitable for use in process development and pilot-scale synthesis under GMP-like conditions for clinical-stage materials.

Quality Control

Our production of this advanced synthetic intermediate adheres to strict quality protocols to ensure batch-to-batch consistency and high chemical purity. Each lot is characterized by comprehensive analytical techniques including NMR, HPLC, and mass spectrometry. A detailed Certificate of Analysis (COA) is provided with every shipment, confirming identity, purity, and conformity to customer specifications. We support development under quality systems suitable for non-GMP and GMP-grade requirements upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container should be kept in a desiccated environment to prevent moisture uptake. For long-term storage, consider using an inert atmosphere (argon or nitrogen) to maintain stability.
