Description

Galnac-Beta1-4Gal CAS NO 34621-75-5 is a specialized carbohydrate derivative, specifically a disaccharide composed of N-acetylgalactosamine (GalNAc) and galactose (Gal) linked via a β-1,4 glycosidic bond. This compound is of significant interest as a key intermediate and biochemical tool in glycobiology research and pharmaceutical development. It is primarily utilized by researchers and manufacturers in the biotechnology, pharmaceutical, and diagnostic sectors for synthesizing complex glycoconjugates, studying carbohydrate-protein interactions, and developing novel therapeutics.

Application

• Glycobiology Research: As a critical building block for the chemical and enzymatic synthesis of complex oligosaccharides, glycopeptides, and glycolipids.
• Pharmaceutical Intermediates: Used in the development of carbohydrate-based drugs, including selectin inhibitors and other therapeutics targeting cell adhesion processes.
• Diagnostic Reagent Synthesis: Serves as a precursor for manufacturing reagents used in assays for detecting specific glycosyltransferases or carbohydrate-binding proteins.
• Enzyme Substrate Studies: Employed as a substrate to study the activity, specificity, and inhibition of glycosidases and glycosyltransferases.
• Cell Surface Mimetics: Used to create neoglycoconjugates for probing cell-surface recognition events and immune responses.
• Standards and References: Acts as a high-purity analytical standard for chromatography (HPLC, LC-MS) in carbohydrate analysis.

Quality Control

Our Galnac-Beta1-4Gal is produced under stringent quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity, NMR for structural confirmation, and specific optical rotation measurement, to ensure identity, potency, and consistency. We provide Certificates of Analysis (COA) with detailed results for all critical parameters. Our quality commitment aligns with the standards required for research and development applications.

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 product is hygroscopic (moisture-sensitive); therefore, the container must be kept tightly sealed in a dry environment to prevent absorption of moisture. For long-term storage, consider desiccants or inert atmosphere.
