Molecular Weight of Ferric Pyrophosphate: Key Facts and Applications

Understanding Ferric Pyrophosphate

Ferric pyrophosphate (Fe₄(P₂O₇)₃) is an iron supplement commonly used in food fortification and pharmaceuticals. Its molecular weight is a crucial parameter for dosage accuracy and formulation stability.

Calculating the Molecular Weight

The molecular weight of ferric pyrophosphate is determined by summing the atomic masses of its constituent elements:

– Iron (Fe): 55.845 g/mol × 4 = 223.38 g/mol
– Phosphorus (P): 30.974 g/mol × 6 = 185.844 g/mol
– Oxygen (O): 15.999 g/mol × 21 = 335.979 g/mol

Total Molecular Weight = 223.38 + 185.844 + 335.979 ≈ 745.20 g/mol

Importance in Industry

1. Food Fortification – Used in cereals and infant formulas to prevent iron deficiency.
2. Pharmaceuticals – A key ingredient in iron supplements due to its bioavailability.
3. Water Treatment – Acts as a phosphate source in certain applications.
