CAS 68957-94-8: Propylphosphonic anhydride

Description: Propylphosphonic anhydride, with the CAS number 68957-94-8, is an organophosphorus compound characterized by its anhydride structure, which is derived from phosphonic acid. It typically appears as a colorless to pale yellow liquid and is known for its high reactivity, particularly in the presence of water, where it can hydrolyze to form phosphonic acids. This compound is often utilized as a reagent in organic synthesis, particularly in the preparation of phosphonates and phosphonic acid derivatives. Its properties include a relatively high boiling point and a low vapor pressure, indicating it is stable under standard conditions but can be sensitive to moisture. Propylphosphonic anhydride is also recognized for its role as a coupling agent in various chemical reactions, making it valuable in both industrial and laboratory settings. Safety precautions are necessary when handling this substance, as it can be corrosive and may pose health risks if inhaled or ingested. Proper storage in a cool, dry place is essential to maintain its stability and reactivity.
