Tributyl(triphenyl)phosphonium bromide hasfound extensive applications in electronics, construction materials, and
plastics industries. Thanks to its outstanding flame retardancy, it has become an indispensable flame retardant for fire-resistant coatings, plastic products, and electronic components.

Triphenylphosphine is a key reagent in thesynthesis of pharmaceuticals, including vitamin D2, vitamin A, and clindamycin.
It also finds applications in the synthesis of plant pigments.

Triphenylphosphine has variousapplications, including serving as a polymerization initiator, a precursor for
antibiotics such as clindamycin, and a standard sample for phosphorus
determination in organic microanalysis.

Triphenylphosphine can be used as abrightener, heat stabilizer, light stabilizer, antioxidant, flame retardant, antistatic agent, rubber antiozonant, and analytical reagent.

Tributyl borate is widely used as an intermediate in the preparation of borohydrides and finds applications in the synthesis of rubber additives, lubricant additives, semiconductor boron diffusion dopants, flame retardants, adhesives, and as a desiccant for anhydrous systems.

Triphenylphosphine serves as a vital ligandin homogeneous catalysts, finding extensive applications in both the
petrochemical and fine chemical industries.
