My ancient (1984—Sixth edition) copy of Sax “Dangerous Properties of Industrial Materials” doesn’t have data for mice, but the water oral LDLo for rabbits is given as 368mg/kg and the intravenous LDLo for rabbits is 13 mg/kg. So I suppose intravenous LD50 of 25 might be about right. Couldn’t find saline which is what is normally injected into blood—it may be significantly higher.
