Description

Arsenic Trichloride is a highly reactive inorganic compound primarily used as a versatile precursor and reagent in advanced chemical synthesis. Its value lies in its ability to act as a potent chlorinating and arsenic-introducing agent, facilitating the production of specialized organoarsenic compounds and other fine chemicals. This product is essential for research laboratories and industrial manufacturers in the semiconductor, pharmaceutical, and specialty chemical sectors who require high-purity intermediates for complex synthesis.

Application

• Chemical Synthesis Precursor: A key starting material for the production of organoarsenic compounds, including pharmaceuticals and agrochemicals.
• Semiconductor Manufacturing: Used in chemical vapor deposition (CVD) processes for doping and creating gallium arsenide (GaAs) and other III-V semiconductor materials.
• Chlorination Agent: Serves as a potent chlorinating reagent in organic synthesis for specific transformations where milder agents are ineffective.
• Catalyst Preparation: Employed in the synthesis and modification of catalysts used in various petrochemical and polymerization reactions.
• Research & Development: A critical reagent in academic and industrial R&D for exploring new materials and synthetic pathways.
• Specialty Glass & Ceramics: Used in the formulation of specialty glasses and ceramics that require specific optical or electronic properties.

Quality Control

Our Arsenic Trichloride is manufactured under stringent controls to ensure high purity and batch-to-batch consistency. Quality is verified through a comprehensive suite of analytical techniques including titration, gas chromatography (GC), and atomic absorption spectroscopy (AAS). A Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment to guarantee compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from incompatible materials such as strong bases, amines, and oxidizing agents. Due to its highly volatile and moisture-sensitive nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent hydrolysis and oxidation. Recommended long-term storage temperature is 2-8°C.
