1. Pesticide Industry
Used as a specialized catalyst in the synthesis process of emamectin benzoate (a highly effective insecticide). (Key catalyst)

2. Organic Synthesis
• Widely used as a highly efficient phosphorylating agent in the preparation of symmetrical phosphodiester compounds.
(Phosphorylating agent)
• As a multifunctional activating agent, it can be used for: inducing the condensation of carboxylic acids with sulfides to produce thioesters; activating DMSO in the Pfitzner-Moffatt reaction to oxidize alcohols to aldehydes or ketones; promoting the halogenation reaction of β-diketones, etc. (Activating agent)

3. Pharmaceutical Synthesis
Used as a reagent in scientific research for the synthesis of nucleotide prodrugs against hepatitis C virus (HCV). (Pharmaceutical intermediate)

4. Polymer Materials
Used as an initiator or modifier in polymerization reactions for the synthesis of phosphate ester derivatives such as flame retardants and plasticizers. (Initiator/Modifier)

5. General Intermediates and Additives
Used as an intermediate in organic synthesis; as a coupling agent for the polymerization of sulfinic acids with alcohols, amines, etc.; as a dehydrating agent in the oxidation reaction of dimethyl sulfoxide (DMSO). (Intermediate/Additive)
