Tris(trimethylsilyl) phosphite is a silyl-protected phosphite that appears as a colorless to light-yellow liquid. It is a mild phosphorylating reagent used in the Arbuzov reaction and as a film-forming additive for lithium-ion battery electrolytes.

1. Serves as a reagent for the mild preparation of bis(trimethylsilyl) phosphonates via the Arbuzov reaction.
2. Functions as a film-forming additive to enhance the electrochemical performance of high-nickel NMC/Si-graphite lithium-ion cells.
3. Used as a critical precursor in multi-step synthesis pathways for active pharmaceutical ingredients.
4. Provides a silylating agent for phosphites and phosphorus-containing specialty chemicals.
