Description

Propargyl-Peg5-β-D-Galactose CAS NO 1397682-63-1 is a specialized, click chemistry-ready derivative of D-galactose featuring a propargyl group linked via a pentaethylene glycol (PEG5) spacer. This compound is engineered for high-value bioconjugation applications, enabling precise and efficient attachment to azide-functionalized molecules under mild, bio-orthogonal conditions. It is an essential building block for researchers and manufacturers in pharmaceutical development, diagnostic probe synthesis, and advanced material science, where controlled carbohydrate presentation is critical.

Application

• Bioconjugation & Probe Development: Used as a key reagent for click chemistry to label proteins, antibodies, and other biomolecules with galactose motifs for targeted drug delivery and imaging.
• Glycobiology Research: Serves as a versatile tool for studying carbohydrate-protein interactions, lectin binding, and cell surface engineering.
• Diagnostic Assays: Facilitates the synthesis of diagnostic probes and biosensors for detecting specific biological targets.
• Drug Discovery: Enables the construction of antibody-drug conjugates (ADCs) and other therapeutic agents with site-specific glycosylation.
• Material Science: Used to functionalize surfaces, nanoparticles, and polymers with bioactive galactose residues to create smart biomaterials.
• Chemical Biology Toolkits: A critical component in kits for metabolic oligosaccharide engineering and glycan remodeling studies.
