Used as a key reagent in organic synthesis for the preparation of phosphite esters, which are intermediates in the production of organophosphorus compounds.

Applied in the synthesis of flame retardants, where it contributes to enhancing the fire resistance of materials such as plastics and textiles.

Utilized in the pharmaceutical industry for the preparation of nucleotide analogs, which are essential in antiviral and anticancer drug development.

Acts as a phosphitylating agent in the modification of nucleosides and nucleotides, playing a critical role in the synthesis of oligonucleotides for genetic research and diagnostics.

Also employed in the production of agrochemicals, including pesticides and herbicides, where it helps in creating compounds with improved efficacy and stability.

Handled with care due to its reactive nature, requiring controlled conditions to ensure safety and effectiveness in various applications.
