2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
guideline study with acceptable restrictions
Qualifier:
according to guideline

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
