Description

Liquoid CAS NO 9056-83-1 is a high-purity, synthetic polyanetholesulfonic acid sodium salt, widely recognized as a key reagent in clinical diagnostics and microbiology. Its primary value lies in its potent anticoagulant and complement-inactivating properties, which are critical for ensuring the accuracy of blood culture systems and other biological assays. This product is essential for manufacturers and laboratories in the in-vitro diagnostic (IVD), pharmaceutical research, and biotechnology sectors who require a reliable and consistent component for microbial growth media and sample preparation.

Application

• Primary anticoagulant in commercial and laboratory-prepared blood culture bottles and systems.
• Component in microbiological culture media for the isolation of fastidious organisms.
• Used as a complement inhibitor in serological tests and immunological assays.
• Reagent in clinical hematology for specialized sample processing.
• Research applications in bacteriology and virology for studying pathogen growth.
• Potential use in molecular biology buffers where nuclease inhibition is required.

Quality Control

Our Liquoid is manufactured under strict quality management systems to ensure batch-to-batch consistency and performance. Each lot is tested to meet stringent specifications for identity, purity, and biological activity relevant to its use in diagnostic applications. A comprehensive Certificate of Analysis (COA) detailing assay, impurity profile, and functional performance is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place 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 performance.
