    Applications

    1. Electronics Industry: Used as a semiconductor dopant and raw material for high-purity phosphorus; plays a critical role in controlling contamination and improving the yield of integrated circuits.
    2. Agrochemicals: Intermediate for the production of organophosphorus pesticides such as DDVP (Dichlorvos) and Isoprothiolane.
    3. Chemical Industry: Key raw material for producing phosphorus oxychloride (POCl₃), phosphorous acid (H₃PO₃), triphenyl phosphate (TPP), and tricresyl phosphate (TCP).
    4. Pharmaceuticals: Intermediate for sulfa drugs such as sulfadiazine and sulfamethoxypyridazine.
    5. Dyes: Used as a condensation agent in the synthesis of azo dye intermediates.
    6. Flavors & Fragrances: Functions as a chlorinating agent and catalyst in fragrance production.
    7. Organic Synthesis: Acts as a chlorinating reagent; reacts with heteroatom compounds (O, N, S), dienes, and organometallics, serving as an essential phosphorus source for ligand synthesis.

    FAQ - Technical & Supply Chain

    • Q:

      Are phosphorus trichloride and phosphorus(III) chloride the same substance?

      A: Phosphorus trichloride and phosphorus(III) chloride are different naming conventions for the same compound identified by CAS 7719-12-2.
    • Q:

      Is phosphorus trichloride mainly supplied as an industrial intermediate?

      A: It is typically supplied as an industrial intermediate for organophosphorus synthesis and downstream chemical manufacturing rather than for laboratory-scale research use.
