Description

Anhydrogalacturonic Acid is a key intermediate and derivative of pectin, characterized by its galacturonic acid backbone with an anhydro linkage. This compound is valued for its role in research and development, particularly in the study of carbohydrate chemistry, pectin structure, and as a precursor for specialized biochemical synthesis. It serves the needs of research institutions, pharmaceutical development labs, and specialty chemical manufacturers focused on advanced biomaterials and analytical standards.

Application

• Biochemical Research: Used as a standard or intermediate in the study of pectin degradation, carbohydrate metabolism, and enzyme substrate specificity.
• Pharmaceutical Development: Investigated as a potential precursor or building block for novel drug delivery systems or bioactive compounds.
• Analytical Chemistry: Serves as a reference standard for chromatographic (HPLC, GC) and spectroscopic methods in quality control labs.
• Food Science Research: Employed in studies related to pectin functionality, texture modification, and dietary fiber analysis.
• Specialty Chemical Synthesis: Acts as a starting material for the synthesis of modified carbohydrates, surfactants, or chelating agents.
• Cosmetic Ingredient Research: Explored for potential applications in skincare formulations due to its carbohydrate-based structure.

Quality Control

Our Anhydrogalacturonic Acid is produced under controlled conditions to ensure batch-to-batch consistency and high purity. Each lot undergoes rigorous analytical testing, including identification and assay by validated methods. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment to support your quality assurance protocols.

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 tightly sealed after opening to prevent absorption of atmospheric moisture, which can affect stability and handling properties.
