Description

Polyanetholesulfonic Acid Sodium Salt is a high-purity, synthetic polyanionic compound widely recognized for its unique biological and chemical properties. This product is essential for applications requiring a consistent and reliable source of a strong polyelectrolyte with anticoagulant and protein-binding characteristics. It serves as a critical reagent in clinical diagnostics, biochemical research, and specialized industrial processes. Our supply ensures the stringent quality and batch-to-batch consistency demanded by these advanced sectors.

Application

• Clinical Diagnostics & Blood Collection: Primarily used as an anticoagulant in blood culture media (e.g., in BACTEC bottles) to inhibit the clotting cascade and neutralize antimicrobial properties of blood, improving microbial recovery rates.
• Biochemical Research: Employed in protein purification and analysis to prevent nonspecific binding and as a component in buffers for electrophoresis and chromatography.
• Virology & Microbiology: Acts as an inhibitor of complement activity and certain enzymes, facilitating the isolation and study of viruses and fastidious microorganisms from biological samples.
• Polymer & Material Science: Serves as a model polyelectrolyte for studying ionic interactions, membrane processes, and for creating functionalized surfaces or hydrogels.
• Pharmaceutical Development: Investigated for use in drug delivery systems and as an excipient due to its polyanionic nature and biocompatibility.

Quality Control

Our Polyanetholesulfonic Acid Sodium Salt is manufactured under a strict quality management system. Each batch is subjected to comprehensive analytical testing to ensure it meets precise specifications for identity, purity, and performance in critical applications like clinical diagnostics. A Certificate of Analysis (COA) detailing assay, molecular weight distribution, and impurity profiles is provided with every shipment to guarantee traceability and compliance.

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). This material is hygroscopic (moisture-sensitive); ensure the container is sealed tightly after each use to prevent absorption of atmospheric moisture, which may affect performance and stability.
