For example, similar to the case made by the FMC for butyllithium, the sponsor for benzene phosphinic acid (phenylphosphinic acid) proposed no additional mammalian toxicology testing because existing animal data showed that administration by oral gavage causes gastrointestinal tract bleeding, necrosis, and occasionally perforation, and the corrosive effects of this substance had already been demonstrated as the basis for its toxicity (BPD/BPA Coalition 2003).
