3-cyclohexylaminopropane-1-sulphonic acid

Boiling point

Administrative data

Endpoint:

boiling point

Data waiving:

study scientifically not necessary / other information available

Justification for data waiving:

the study does not need to be conducted because the substance is a solid which decomposes before boiling

Justification for type of information:

JUSTIFICATION FOR DATA WAIVING
Decomposition temp. is ca. 327 °C (exp.), see IUCLID section 4.2.

Cross-reference

Reason / purpose for cross-reference:

data waiving: supporting information

Reference

2 (reliable with restrictions)

Rationale for reliability incl. deficiencies:

guideline study with acceptable restrictions

Qualifier:

according to guideline

Guideline:

OECD Guideline 102 (Melting point / Melting Range)

Type of method:

capillary method

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
