Why ≥99% by HPLC is stated with its method
Purity is reported as a figure and a method together. The figure is ≥99%; the method is HPLC. Identity of the Ala-Glu-Asp-Gly sequence is confirmed separately by mass spectrometry. Both appear on the certificate of analysis issued for the lot in the shipment.
The molecular data support verification in the receiving laboratory. Molecular formula is C14H22N4O9. Molecular weight is 390.3 g/mol. CAS number 307297-39-8 identifies the compound in purchasing and inventory systems. The material is a lyophilized powder and is sold for research use only.
