Identity (LC-MS)Mass identified as FOX04-DRI · compound named: FOX04-DRI · mass identification table: FOX04-DRI: 99.83%Mass spectrometry measures the molecular mass of what's in the vial and compares it with the declared compound. "Confirmed" means the lab found the expected compound. Expected average molecular weight of FOXO4-DRI (PubChem): 5358 g/mol. The observed mass appears in the certificate's chart and isn't transcribed here.Reported as matching the declared compound
