Applicant's summary and conclusion
- Conclusions:
- The study was performed according to OECD TG102 without deviations and therefore reliability of Klimisch 2 has been assigned. The melting range of the test material has been determined to be 245.4 - 249.3 °C (mean value).
- Executive summary:
The melting point / melting range of the test substance was determined in a non-GLP test according to OECD 102.
The test material 3-[(aminoiminomethyl)thio]propanesulphonic acid melts between 245.4 - 249.3 °C.
