Description

Sodium Cacodylate Trihydrate CAS NO 6131-99-3 is the trihydrate form of sodium cacodylate, an organoarsenic compound. It serves as a critical buffering agent in biological and biochemical research, particularly for electron microscopy and histology. This product is essential for laboratories and manufacturers in the life sciences, pharmaceutical development, and industrial research sectors requiring precise pH control in specialized applications.

Application

• Electron Microscopy Buffer: A primary component in cacodylate buffer formulations for fixing and washing tissue samples in transmission and scanning electron microscopy (TEM/SEM).
• Histological Staining: Used as a buffer in staining procedures to maintain optimal pH for dye binding and tissue morphology preservation.
• Biochemical Research: Employed in various enzymatic and protein studies where a stable, non-phosphate buffer system is required.
• Pharmaceutical Intermediate: Acts as a precursor or intermediate in the synthesis of certain organoarsenic compounds and specialty chemicals.
• Veterinary and Agricultural Research: Historically used in some research applications, though modern use is highly specialized and controlled.

Quality Control

Our Sodium Cacodylate Trihydrate is manufactured under a rigorous quality management system. Each batch is tested to ensure it meets high-purity standards suitable for research applications. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and assay is provided with every shipment to guarantee traceability and compliance with your laboratory's requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after use to prevent absorption of atmospheric moisture.
