Description

Trisodium Arsenate is an inorganic salt of arsenic acid, widely recognized by its CAS number 13464-38-5. This compound serves as a critical source of arsenic in controlled industrial processes, valued for its stability and defined chemical composition. It is primarily utilized in specialized manufacturing sectors such as glass production, metallurgy, and as a precursor in certain chemical syntheses where precise arsenic content is required.

Application

• As a clarifying and decolorizing agent in the manufacture of specialty glass and ceramics.
• In metallurgical processes for alloy formation and surface treatments.
• As a starting material or intermediate in the synthesis of other arsenic-containing compounds for research and industrial use.
• In wood preservation treatments, subject to strict regulatory compliance and handling protocols.
• For use in analytical chemistry as a standard or reagent.
• In limited, highly controlled applications within the electronics industry for semiconductor doping.

Quality Control

Our Trisodium Arsenate is manufactured under stringent quality control protocols to ensure batch-to-batch consistency and reliability. Each lot is analyzed to confirm identity, purity, and conformance to agreed specifications. A comprehensive Certificate of Analysis (COA) detailing assay results and impurity profiles is provided with every shipment to support your quality assurance processes.

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 to prevent absorption of atmospheric moisture. Keep away from incompatible materials.
