1-(3-sulphonatopropyl)pyridinium

Acute Toxicity: other routes

Administrative data

Endpoint:

acute toxicity: other routes

Type of information:

(Q)SAR

Adequacy of study:

supporting study

Reliability:

2 (reliable with restrictions)

Rationale for reliability incl. deficiencies:

other: see 'Remark'

Remarks:

A real grade of toxicity of a NOAEL is not possible to evaluate with the aid of the modeling tool. It delivers only information about “direction” of toxicity and states that the substance is of unknown toxicity (“Class III” according to the modeling tool).

Justification for type of information:

QSAR prediction: migrated from IUCLID 5.6

Results and discussion

Effect levels

Dose descriptor:

other: Prediction

Effect level:

other: Class III substances are those that permit no strong initial presumption of safety, or may even suggest significant toxicity or have reactive functional groups

Based on:

other: QSAR rules evaluating structural alerts

Remarks on result:

other: Substance allocated in the “TOXTREE Toxicity Class III”, which is characteristical for substances with a possibly high level of toxicity. Prediction is based on identification of aromatic ring with complex substituent, a structural alert for toxicity.

Applicant's summary and conclusion

Conclusions:

No prediction was possible for the test substance, as Class III substances are those that permit no strong initial presumption of safety, or may even suggest significant toxicity or have reactive functional groups.

Executive summary:

For 3-(1-Pyridinio)-1-propanesulfonate, no prediction was possible, as it was classified as a Class III substance and those do not permit a strong initial presumption of safety, or may even suggest significant toxicity or have reactive functional groups.
