Reference
Endpoint:
melting point/freezing point
Type of information:
experimental study
Adequacy of study:
key study
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to
Guideline:
other: OECD 102/A1 Melting Freezing Temperature
Deviations:
no
GLP compliance:
yes (incl. certificate)
Type of method:
differential scanning calorimetry
Decomposition:
yes
Decomp. temp.:
ca. 140 °C

Thermal and oxidative decomposition from approximately 140 °C with no definitive signs of melting below 450°C. As the test item decomposed, no value for melting temperature could be determined.

Conclusions:
Diammonium sodium hexakis(nitrito-N)rhodate was determined to decompose from approximately 140 °C (413 K) with no definitive signs of melting below 450 °C (724 K).
Executive summary:

Atwal and Tremain (2011) is a GLP compliant study following OECD guideline 102 and is considered suitable for use as the key study for this endpoint.

Diammonium sodium hexakis(nitrito-N)rhodate was determined to decompose from approximately 140 °C (414 K) with no definitive signs of melting below 450 °C (724 K).
