Description

D-Galactosamine is a vital amino sugar derivative, specifically the 2-amino-2-deoxy form of galactose, widely used in biochemical research and pharmaceutical development. Its primary significance lies in its role as a key precursor and model compound for studying glycosaminoglycan metabolism, liver function, and inflammatory pathways. This high-purity chemical is essential for researchers and manufacturers in the pharmaceutical, biotechnology, and life science sectors, particularly for applications in hepatology research, glycobiology, and the synthesis of complex carbohydrates.

Application

• Pharmaceutical Research & Development: A critical building block for synthesizing glycosaminoglycans (GAGs) like chondroitin sulfate and heparan sulfate, and for developing hepatoprotective drugs.
• Biochemical Studies: Used extensively to induce experimental hepatitis and study liver injury, inflammation, and apoptosis mechanisms in animal models.
• Glycobiology & Glycochemistry: Serves as a fundamental substrate for enzymatic studies, glycosylation reactions, and the chemoenzymatic synthesis of oligosaccharides and glycoconjugates.
• Cell Culture & Microbiology: Employed in media formulations and as a selective agent in microbial and mammalian cell culture studies.
• Diagnostic Reagent Production: Utilized in the manufacture of diagnostic kits and reagents for liver function tests and metabolic disorder assessments.
• Cosmeceutical Ingredient: Investigated for use in advanced skincare formulations for its potential hydrating and skin-barrier repair properties.

Quality Control

Our D-Galactosamine is produced under a stringent quality management system to ensure batch-to-batch consistency and high purity suitable for research and development. Each lot undergoes comprehensive analytical testing, including HPLC for assay and purity, specific optical rotation verification, and tests for residual solvents and heavy metals. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with every shipment to guarantee traceability and compliance with your project requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed in a dry environment to prevent absorption of moisture, which can affect stability and purity.
