Diethyl phosphite

Description:

Diethyl phosphite is an organophosphorus compound characterized by its molecular formula C4H11O3P. It appears as a colorless to pale yellow liquid with a faint odor. This substance is known for its role as a reagent in organic synthesis, particularly in the preparation of phosphonates and phosphonamidates. Diethyl phosphite is soluble in organic solvents such as ethanol and ether but has limited solubility in water. It exhibits moderate toxicity and can act as a potential irritant to the skin, eyes, and respiratory system. The compound is also sensitive to moisture, which can lead to hydrolysis, producing diethyl phosphonate and phosphoric acid. Due to its reactivity, diethyl phosphite is utilized in various applications, including as a precursor in the synthesis of pesticides and pharmaceuticals. Proper handling and storage in a cool, dry place are essential to ensure safety and stability.
