Description

α-D-Xylopyranose, 1,2-o-(1-Ethoxyethylidene)- (9Ci) is a specialized carbohydrate derivative featuring a protective acetal group at the 1,2-positions of the xylose sugar ring. This compound matters as a crucial chiral intermediate and building block in synthetic organic chemistry, enabling the controlled synthesis of complex molecules. It is primarily needed by researchers and manufacturers in the pharmaceutical industry for developing active pharmaceutical ingredients (APIs), as well as by agrochemical and fine chemical producers for creating novel compounds with specific stereochemistry.

Application

• Pharmaceutical Intermediate: Serves as a key chiral synthon in the multi-step synthesis of nucleoside analogs, antiviral agents, and other therapeutic molecules.
• Glycochemistry Research: Used as a protected xylose donor in the study and synthesis of oligosaccharides, glycoconjugates, and carbohydrate-based polymers.
• Agrochemical Synthesis: Acts as a precursor for developing novel, stereochemically-defined pesticides and plant growth regulators.
• Fine Chemical Production: Employed in the manufacture of specialty chemicals, flavors, and fragrances where specific sugar-derived chirality is required.
• Material Science: Potential monomer or cross-linking agent in the development of biodegradable or bio-based polymers and hydrogels.
