Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Administrative data

Endpoint:
acute toxicity: oral
Type of information:
experimental study
Adequacy of study:
key study
Study period:
1972
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: Details on methodology are given. Large number of animals used (ca. 100). This data is probably the basis for the HSDB entry, see under 7.3.1.001, as the result is the same oral LD50 (rabbit). That HSDB entry is **PEER REVIEWED**

Effect level:
7 410 mg/kg bw

Any other information on results incl. tables

Results:

Larger doses caused disappearance of corneal reflexes, nystagmus, dyspnea and bradycardia.

ND50: 32 mmol/kg (= 4160 mg/kg; calculated with a molar mass of 130)

LD50: 57 mmol/kg (= 7410 mg/kg; calculated with a molar mass of 130)
