Description

Dextrin 2-Sulfate is a chemically modified polysaccharide derivative, where sulfate groups are introduced onto the dextrin backbone. This sulfation process significantly enhances the compound's functional properties, making it valuable for applications requiring specific ionic characteristics and solubility profiles. It is particularly sought after by manufacturers in the pharmaceutical, cosmetic, and specialty chemical industries for its utility as an excipient, stabilizer, or functional intermediate.

Application

• Pharmaceutical Excipient: Used as a tablet disintegrant, binder, or controlled-release matrix component in solid dosage forms.
• Biochemical Research: Serves as a substrate or inhibitor in enzymatic studies, particularly those involving sulfatases or glycosaminoglycan interactions.
• Cosmetic Formulations: Acts as a viscosity modifier, stabilizer, or skin-conditioning agent in creams, lotions, and gels.
• Industrial Processes: Functions as a dispersing agent, sizing agent, or temporary protective coating in various manufacturing processes.
• Dietary Supplement Carrier: Potential use as a carrier for micronutrients or active ingredients in supplement formulations.

Quality Control

Our Dextrin 2-Sulfate is produced under a rigorous quality management system. Each batch is tested to ensure consistent sulfation degree, purity, and functional performance. While specific grades can be tailored, our standard quality commitment includes testing for identity, assay, residual solvents, and heavy metals. A comprehensive Certificate of Analysis (COA) is provided with every shipment.

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 opening to prevent moisture absorption, which can affect product performance.
