This technical note provides evidence for the degradation of Tris buffer in a peptide formulation stored at elevated temperature (70°C). The buffer degrades to liberate formaldehyde, which is shown to react with the peptide tyrosine residue. Those involved in peptide/protein formulation should be aware of the possible instability in this common biological buffer. © 2001 Wiley‐Liss, Inc. and the American Pharmaceutical Association J Pharm Sci 90:1198–1203, 2001
