How it works
The math
Sum of atomic masses
MW = Σ (element mass × atom count)
Retatrutide, C₂₂₁H₃₄₂N₄₆O₆₈, sums to ≈ 4,731 g/mol with standard atomic weights. Product pages list molecular weights from vendor certificates, which may follow slightly different rounding or monoisotopic conventions.
Uses standard atomic weights (IUPAC). For laboratory research use.
