I'm sure one of the impurities is endotoxin; but because this is measured AFTER formulation into LNPs, I think this has to do with the adducts, aldehydes and who knows what else.
Intermediaries, metals and elements, Tris contaminants would be measured upstream, I think.
But why is Pfizer not testing? Because they don't have to?
Known significant impurities in Tromethamine that can potentially cause health problems include:
2-amino-1,3-propanediol (APD)
2-amino-2-methyl-1,3-propanediol (AMPD)
2-(N-methylamino)-1,3-propanediol (MMAPD)
2-(N-methylamino)-2-hydroxymethyl-1,3-propanediol (MMTA)
2-(N,N-dimethylamino)-2-hydroxymethyl-1,3-propanediol (DMTA).
