Industrial uses
Sodium trimetaphosphate, Na3[P3O9], is the most stable compound of this group of reagents. The hydrated form of sodium trimetaphosphate contains 6 or 10 molecules of water of crystallization. Commercial production is obtained by heating NaPO3 at 525 °C.
Safety Profile
Poison by intravenous route. Moderately toxic by intraperitoneal route. When heated to decomposition it emits toxic fumes of POx and Na2O. See also PHOSPHATES.
Purification Methods
It is precipitated from an aqueous solution at 40o by adding EtOH. It is dried in air.
Check Digit Verification of cas no
The CAS Registry Mumber 7785-84-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,7,8 and 5 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 7785-84:
(6*7)+(5*7)+(4*8)+(3*5)+(2*8)+(1*4)=144
144 % 10 = 4
So 7785-84-4 is a valid CAS Registry Number.
