Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Key result
Decomposition:
yes
Decomp. temp.:
ca. 327 °C
Remarks on result:
other: no atm. pressure given
Conclusions:
The test material 3-(cyclohexylamino)propane-1-sulfonic acid decomposes before melting occurs.
Mean decomposition temperature : approx. 327°C
The study was performed according to OECD TG102 without deviations and therefore reliability of Klimisch 2 has been assigned.
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 -(cyclohexylamino)propane-1 -sulfonic acid decomposes before melting occurs.

Decomposition temperature measurement 1 : approx. 328°C

Decomposition temperature measurement 2 : approx. 326°C

Mean decomposition temperature : approx. 327°C

Description of key information

No melting point has been determined, the test material decomposes (at ca. 327 °C) before melting occurs. [OECD Guideline 102]

Key value for chemical safety assessment
