Description

Galacturonic Acid is a key uronic acid derived from pectin, serving as a fundamental building block in polysaccharide chemistry and biochemistry. Its significance lies in its role as a precursor for the synthesis of ascorbic acid (Vitamin C) and various biochemical intermediates. This high-purity compound is essential for research and development laboratories, pharmaceutical manufacturers, and the food science industry, where it is used in analytical standards, enzymatic studies, and product formulation.

Application

• Pharmaceutical Intermediate: Critical precursor in the chemical and enzymatic synthesis of L-ascorbic acid (Vitamin C) and other bioactive molecules.
• Biochemical Research: Used as a substrate for enzymes like pectinase and polygalacturonase in metabolic pathway studies and enzyme characterization.
• Analytical Standard: Serves as a high-purity reference standard in HPLC, GC, and other chromatographic methods for quantifying pectin derivatives and uronic acids.
• Food Science & Technology: Employed in studies related to pectin gelation, food texture modification, and as a model compound for dietary fiber analysis.
• Cosmetic Ingredients: Investigated for use in skincare formulations for its potential hydrating and film-forming properties derived from its carbohydrate structure.
• Microbiology & Fermentation: Acts as a carbon source in specific microbial culture media for the selective growth and study of certain bacterial strains.

Quality Control

Our Galacturonic Acid is manufactured under a strict quality management system. Each batch is subjected to comprehensive analytical testing, including identity confirmation, purity assay, and impurity profiling to ensure it meets the high standards required for research and industrial use. Certificates of Analysis (COA) detailing all test results are provided to guarantee traceability, consistency, and compliance with your specifications.

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 nature, the container must be kept tightly sealed after each use to prevent moisture absorption, which can affect stability and handling properties.
