Sodium monofluorophosphate

Molecular formula：Na₂PO₃F　Molecular weight：143.95
Usage: The source of fluoride for effective toothpaste used to protect teeth is a toothpaste abrasive, anti caries agent, and desensitizer, with a general dosage of 0.8%. It is also used as a fluoride disinfectant for drinking water and a metal surface cleaner, and is a raw material for preparing other monofluorophosphate salts.
Property: Colorless fine crystals or white powder. Decompose and release hydrogen fluoride in humid air. Easy to dissolve in water, the solution is neutral. It is easily hydrolyzed in acidic solutions and decomposes into pyrophosphate upon heating, with a melting point of 625 ℃.
CAS#：10163-15-2　Customs number：2826909090　MSDS：YF0405-03　Hazard code：non-dangerous goods
