Description

L-Glycero-L-Galacto-Heptitol, 2,6-Anhydro-3,4,5-Tris-o-(Phenylmethyl)-, 7-(4-Methylbenzenesulfonate) is a sophisticated, high-purity synthetic intermediate characterized by its protected heptitol structure and activated sulfonate ester group. This compound matters for its role as a critical building block in the synthesis of complex carbohydrates, nucleosides, and glycoconjugates, enabling precise chemical transformations. It is primarily needed by research institutions and pharmaceutical companies engaged in advanced medicinal chemistry, carbohydrate chemistry, and the development of novel therapeutics and diagnostic agents.

Application

• Pharmaceutical Intermediate: Serves as a key precursor in the synthesis of novel nucleoside analogs and carbohydrate-based active pharmaceutical ingredients (APIs).
• Glycochemistry Research: Used as a protected glycosyl donor or acceptor for constructing complex oligosaccharides and glycoconjugates in academic and industrial R&D.
• Medicinal Chemistry: Employed in structure-activity relationship (SAR) studies and the development of glycosidase inhibitors or other carbohydrate-targeting drugs.
• Bioconjugation: The activated tosylate group enables its use in linker chemistry for attaching carbohydrate motifs to proteins, peptides, or other biomolecules.
• Process Chemistry Development: Utilized in route scouting and optimization for the scalable production of high-value fine chemicals.
• Standards and Reference Material: Supplied as a high-purity analytical standard for method development and quality control in related synthetic workflows.
