122-52-1 - Application:

Triethyl Phosphite (TEP) (CAS: 122-52-1) has a strong foul odor. Insoluble in water; soluble in alcohol and ether. Combustible.Vapors heavier than air. Uses: Synthesis, plasticizers, stabilizers, lubricant and grease additives. Triethyl Phosphite is an organophosphorus compound. It is used as a reducing agent; can react with electrophiles to form phosphonates or phosphates; forms a stable complex with copper(I) iodide. Triethyl Phosphite is a very good nucleophile. The carbon adjacent to the bromine is the most electrophilic position, and phosphorus is the only nucleophile. Triethyl Phosphite is moderately toxic liquid, combustible. Flammable when exposed to heat or flame. When heated to decomposition Triethyl Phosphite emits toxic fumes of oxides of phosphorus.
