CAS 122-52-1

Triethyl phosphite

Description:

Triethyl phosphite, with the CAS number 122-52-1, is an organophosphorus compound characterized by its three ethyl groups attached to a phosphorus atom. It is a colorless to pale yellow liquid with a faint odor and is soluble in organic solvents such as alcohol and ether, but only slightly soluble in water. Triethyl phosphite is known for its role as a versatile reagent in organic synthesis, particularly in the preparation of phosphonates and phosphonyl compounds. It exhibits properties such as being a nucleophile and a reducing agent, making it useful in various chemical reactions, including the synthesis of esters and the phosphorylation of alcohols. Additionally, it can act as a stabilizer in certain polymer formulations. However, it is important to handle triethyl phosphite with care, as it can be toxic and may cause irritation upon contact with skin or eyes. Proper safety measures, including the use of personal protective equipment, are essential when working with this chemical.
