Description

Diisooctylthiophosphinic Acid is a specialized organophosphorus compound primarily utilized as an effective extractant and complexing agent. Its value lies in its strong chelating properties, particularly for heavy and transition metals, making it a critical component in advanced separation processes. This product is essential for industries involved in hydrometallurgy, metal recovery, and the production of high-purity chemicals.

Application

• As a selective solvent extractant for the separation and purification of cobalt, nickel, and copper from leach solutions in hydrometallurgy.
• In the recovery of precious metals like platinum, palladium, and gold from secondary sources and industrial waste streams.
• As a key component in liquid-liquid extraction processes for the removal of metal impurities from process streams in the chemical industry.
• In the formulation of specialty catalysts and as a ligand in organometallic synthesis.
• For the purification of rare earth elements (REEs) and other critical minerals.
• As a stabilizer or additive in specific polymer and lubricant formulations requiring metal deactivation.

Quality Control

Our Diisooctylthiophosphinic Acid is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including assay by titration and impurity profile analysis, to ensure consistency and performance for demanding extraction applications. Certificates of Analysis (COA) documenting purity, acidity, and physical properties are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials such as strong bases and oxidizing agents. Due to its nature as a strong acid/organic solvent, containers should be kept tightly sealed to prevent moisture absorption and degradation. Recommended storage temperature is 15-25°C.
