CAS 589-57-1

Diethyl chlorophosphite

Description:

Diethyl chlorophosphite, with the CAS number 589-57-1, is an organophosphorus compound characterized by its chemical formula C4H10ClO2P. It appears as a colorless to pale yellow liquid with a pungent odor. This compound is known for its reactivity, particularly as a phosphorus-containing reagent in organic synthesis. It is commonly used in the preparation of various phosphonates and phosphonylated compounds, which are important in the development of pharmaceuticals and agrochemicals. Diethyl chlorophosphite is sensitive to moisture and can hydrolyze in the presence of water, releasing hydrochloric acid and forming diethyl phosphite. Due to its potential toxicity and corrosive nature, it requires careful handling and storage under controlled conditions. Safety measures, including the use of personal protective equipment, are essential when working with this substance to prevent exposure and ensure safe laboratory practices.
