Reference
Endpoint:
melting point/freezing point
Type of information:
read-across from supporting substance (structural analogue or surrogate)
Adequacy of study:
weight of evidence
Justification for type of information:
Target and source substances are highly similar, both structurally and chemically.
Reason / purpose for cross-reference:
read-across source
Qualifier:
according to guideline
Guideline:
OECD Guideline 102 (Melting point / Melting Range)
Deviations:
no
GLP compliance:
no
Remarks on result:
not determinable
Remarks:
No melting point could be referred to the test item. The melting/freezing point must be considered as lower than -150°C, as no thermal effect and no crystallisation enthalpy could be observed.
Conclusions:
No melting point could be referred to LOWER-7.
Executive summary:
Uronium hydrogen sulphate was tested according to OECD guideline 102 (non-GLP).

No melting/freezing point could be referred to the test item up to -150°C.

Description of key information

No melting/freezing point could be referred to the test item up to -150°C.

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
-150 °C
