Description

Arsenic(V) CAS NO 17428-41-0 refers to pentavalent arsenic compounds, a critical class of inorganic chemicals essential for specialized industrial synthesis and research. This high-purity material is valued for its role as a precise precursor in the development of advanced electronic materials and specialized reagents. It is primarily utilized by manufacturers and research institutions in the semiconductor, specialty chemical, and analytical reagent sectors.

Application

• Semiconductor Manufacturing: Used as a doping agent or precursor material in the production of gallium arsenide (GaAs) and other III-V compound semiconductors.
• Specialty Chemical Synthesis: Serves as a key starting material or intermediate for synthesizing organoarsenic compounds and other specialized chemicals.
• Analytical Chemistry: Employed as a standard or reagent in trace metal analysis, environmental testing, and quality control laboratories.
• Research & Development: Utilized in academic and industrial R&D for studying material properties, catalysis, and novel synthetic pathways.
• Wood Preservation: Historically used in the formulation of chromated copper arsenate (CCA) for treated lumber; modern use is highly regulated.
• Glass Manufacturing: Acts as a fining agent to remove bubbles and as a decolorizing agent in specialty glass production.

Quality Control

Our Arsenic(V) is produced and handled under strict quality management protocols to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including assay and impurity profile analysis via techniques like ICP-MS and titration. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed in a dry environment to prevent absorption of atmospheric moisture. Keep away from incompatible materials such as strong acids and organic solvents.
