Description

Antimony-125 is a stable, non-radioactive isotope of the metalloid antimony, identified by CAS NO 14234-35-6. This high-purity material is critical for applications requiring precise elemental composition and minimal isotopic interference. It is primarily utilized in advanced material science, semiconductor research, and as a calibration standard in analytical chemistry. Industries involved in electronics manufacturing, nuclear technology, and specialized chemical synthesis rely on its consistent quality and defined isotopic purity.

Application

• Semiconductor Dopant and Research: Used in the development and calibration of semiconductor materials where precise antimony doping levels are required.
• Analytical Chemistry Standard: Serves as a high-purity calibration standard for techniques like ICP-MS (Inductively Coupled Plasma Mass Spectrometry) and AAS (Atomic Absorption Spectroscopy).
• Advanced Alloy Component: Incorporated into specialized lead-antimony or tin-antimony alloys to enhance hardness and mechanical properties.
• Catalyst Research: Investigated as a component or promoter in catalysts for organic synthesis and polymerization reactions.
• Reference Material in Nuclear Science: Employed in nuclear laboratories as a stable isotopic reference for related radioactive antimony isotopes.
• Flame Retardant Synergist Studies: Used in research and development of next-generation flame retardant systems, often in conjunction with halogenated compounds.

Quality Control

Our Antimony-125 is produced and handled under stringent quality management protocols. Each batch is analyzed to confirm isotopic purity and elemental composition, ensuring it meets the exacting requirements of research and industrial applications. A comprehensive Certificate of Analysis (COA) detailing isotopic abundance, metallic impurities, and other critical parameters is provided with every shipment to guarantee traceability and consistency.

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 nature of being easily oxidized, long-term storage under an inert atmosphere (e.g., argon or nitrogen) is recommended for optimal stability. Keep away from strong acids and strong oxidizing agents.
