Applicant's summary and conclusion
- Conclusions:
- The test material changes after start of melting into decomposition at ca. 255°C.
- Executive summary:
The melting point of the test material sodium 3-[[(dimethylamino)thioxomethyl]thio]propanesulphonate was determined experimentally using the capillary method in a non-GLP test according to OECD guideline 102. The test material changes after start of melting at 243°C into decomposition at ca. 255°C.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
