Description

Diisopropyl Hydrogen Phosphate is a high-purity organophosphorus compound, widely recognized for its utility as a versatile intermediate and reagent in advanced chemical synthesis. Its value lies in its ability to act as a phosphorylating agent and a key building block for more complex phosphate esters and ligands. This product is essential for industries engaged in pharmaceutical development, agrochemical manufacturing, and the production of specialized flame retardants and extractants.

Application

• Pharmaceutical Intermediate: A key synthon in the production of nucleotide analogs, prodrugs, and active pharmaceutical ingredients (APIs).
• Agrochemical Synthesis: Used in the manufacture of organophosphate insecticides, herbicides, and plant growth regulators.
• Ligand & Catalyst Preparation: Serves as a precursor for phosphonate and phosphinate ligands used in homogeneous catalysis and metal extraction processes.
• Flame Retardant Formulation: An intermediate in the synthesis of phosphorus-based flame retardants for polymers and textiles.
• Research & Development: A valuable reagent in organic and medicinal chemistry research for introducing phosphate groups.
• Solvent Extraction: Employed in the formulation of extractants for the separation of rare earth and precious metals.

Quality Control

Our Diisopropyl Hydrogen Phosphate is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing, including assay by titration, identification by FT-IR, and impurity profiling by GC/HPLC, to ensure it meets the high standards required for industrial and research applications. A detailed Certificate of Analysis (COA) is provided with each shipment to guarantee traceability and compliance with your specifications.

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 2-25°C.
