Description

L-Glycero-L-Galacto-Heptitol, 2,6-Anhydro-3,4,5-Tris-o-(Phenylmethyl)-, Bis(4-Methylbenzenesulfonate) is a high-purity, synthetically derived carbohydrate derivative of significant interest in advanced organic synthesis. This compound serves as a critical chiral building block and protected intermediate for the construction of complex oligosaccharides and glycoconjugates. It is essential for researchers and manufacturers in pharmaceutical development, particularly in the synthesis of novel therapeutics, diagnostic agents, and in carbohydrate-based chemical biology.

Application

• Pharmaceutical Intermediate: A key chiral synthon for the synthesis of complex glycomimetics and carbohydrate-based active pharmaceutical ingredients (APIs).
• Glycobiology Research: Used as a protected precursor for constructing defined oligosaccharide sequences to study carbohydrate-protein interactions.
• Diagnostic Reagent Development: Employed in the creation of labeled sugar analogs for imaging and detection assays.
• Chemical Synthesis: Serves as a versatile intermediate in multi-step organic synthesis for introducing specific sugar motifs with defined stereochemistry.
• Academic & Industrial R&D: A valuable tool for chemists developing new synthetic methodologies and exploring the structure-activity relationships of glycosylated compounds.

Quality Control

Our L-Glycero-L-Galacto-Heptitol derivative is manufactured under strict quality systems to ensure batch-to-batch consistency and high chemical purity, suitable for demanding synthetic applications. Each batch is supported by a comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles. We adhere to cGMP principles where applicable, and our quality commitment ensures the material meets the exacting standards required for pharmaceutical R&D and scale-up.

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 (moisture-sensitive) nature, the container must be kept tightly sealed in a dry environment to prevent degradation. For long-term storage, consider using desiccants.
