Description

O,o-Di-sec-Butyl Hydrogen Dithiophosphate is a versatile organophosphorus compound widely utilized as a key intermediate and performance additive. Its primary value lies in its ability to act as an effective ligand and extractant for various metal ions, as well as a precursor for specialized agrochemicals and lubricant additives. This product is essential for manufacturers and R&D facilities in the mining, metallurgy, and specialty chemical synthesis sectors seeking reliable, high-purity intermediates.

Application

• Metal Extraction & Hydrometallurgy: Serves as a selective extractant and collector agent for the recovery of copper, zinc, and other non-ferrous metals from ores and solutions.
• Lubricant & Fuel Additives: Acts as a precursor for the synthesis of anti-wear and extreme pressure (EP) additives, enhancing the performance of industrial lubricants and hydraulic fluids.
• Agrochemical Intermediates: Used in the manufacture of organophosphate-based insecticides and fungicides, where it functions as a critical building block.
• Polymer Stabilizers & Antioxidants: Employed as a stabilizer intermediate to prevent the oxidative degradation of polymers and plastics during processing and service life.
• Coordination Chemistry & Catalysis: Functions as a chelating ligand in the preparation of metal complexes for catalytic applications and research.
• Flotation Agents: Applied in mineral processing as a flotation reagent to improve the separation efficiency of sulfide minerals.

Quality Control

Our O,o-Di-sec-Butyl Hydrogen Dithiophosphate is manufactured under a strict quality management system to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including assay, identity confirmation, and impurity profiling. Certificates of Analysis (COA) documenting all critical parameters are provided and available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area away from heat sources and incompatible materials. Due to its nature as a strong acid/organic solvent and being easily oxidized, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term stability. Keep container tightly sealed when not in use to minimize moisture uptake and oxidation.
