2-chloro-1,3,2-dioxaphospholane

Description:

2-Chloro-1,3,2-dioxaphospholane, with the CAS number 822-39-9, is a cyclic organophosphorus compound characterized by a five-membered ring containing both oxygen and phosphorus atoms. This compound features a dioxaphospholane structure, which includes two oxygen atoms and one phosphorus atom in the ring, along with a chlorine substituent at the 2-position. It is typically a colorless to pale yellow liquid with a distinctive odor. The presence of the chlorine atom enhances its reactivity, making it useful in various chemical synthesis applications, particularly in the preparation of phosphorous-containing compounds. The compound is sensitive to moisture and can hydrolyze in the presence of water, leading to the formation of phosphoric acid derivatives. Its unique structure and reactivity profile make it of interest in organic synthesis and materials science, particularly in the development of flame retardants and other functional materials. Safety precautions are necessary when handling this compound due to its potential toxicity and reactivity.
