CAS 121-45-9

Trimethyl phosphite

Description:

Trimethyl phosphite, with the CAS number 121-45-9, is an organophosphorus compound characterized by its molecular formula C3H9O3P. It appears as a colorless to pale yellow liquid with a faint, sweet odor. This compound is known for its role as a reagent in organic synthesis, particularly in the preparation of phosphonates and phosphonylated compounds. Trimethyl phosphite is soluble in organic solvents such as ethanol and ether, but it is less soluble in water. It is a relatively stable compound under normal conditions, but it can hydrolyze in the presence of moisture, releasing methanol and phosphoric acid. Due to its phosphorus content, it can act as a source of nucleophilic phosphorus in various chemical reactions. However, it should be handled with care, as it can be toxic and irritating to the skin and eyes. Proper safety measures, including the use of personal protective equipment, are essential when working with this substance in a laboratory setting.
