About 1-Propanephosphonic anhydride, 50 wt.% solution in Ethyl acetate

Listed under CAS 68957-94-8, 1-Propanephosphonic anhydride is an organic building block available from Vaqora Chemicals with a typical assay of 50%. Its molecular formula is C9H21O6P3 and its molecular weight is 318.18 g/mol. Systematically, it is named 2,4,6-tripropyl-1,3,5,2lambda5,4lambda5,6lambda5-trioxatriphosphinane 2,4,6-trioxide. It is also known as Propanephosphonic anhydride solution or PPACA.

The material typically appears as a colourless to yellow liquid. Literature values give a density of 1.069 g/mL at 25 °C. Keep the container tightly sealed and store it in a cool, dry area. The GHS classification uses the signal word “Danger”, so appropriate gloves, eye protection and ventilation are recommended.

Key uses span organic synthesis and API synthesis. It is used across pharmaceutical manufacturing and academic and industrial research.

Standard pack sizes are 25 mL, 100 mL and 500 mL, and every batch ships with a Certificate of Analysis (COA) and we export worldwide.
