Toxicological information

Acute Toxicity: oral

Currently viewing:

Administrative data

Endpoint:
acute toxicity: oral
Type of information:
experimental study
Adequacy of study:
supporting study
Study period:
Single exposure
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
data from handbook or collection of data
Justification for type of information:
Data review as part of the US National Toxicity Program (NTP) and considered reliable.
Data taken from review of anhydride, showing that the acid (hydride) quickly forms on ingestion.
Together with further weight of evidence, it is concluded that further animal testing cannot be justified
