Qualifier:
according to guideline
Guideline:
OECD Guideline 102 (Melting point / Melting Range)

Type of method:
other: metal block method
Decomposition:
yes
Decomp. temp.:
>= 300 °C
Sublimation:
no
Remarks on result:
other: no melting up to decomposition temperature

In the duplicate definitive determinations, the samples darkened noticeably from approximately 300 °C, with no sign of melting. This observation was indicative of decomposition.

Conclusions:
The melting temperature was not determinable as DIGIRENA SA TEMABF4 anhydrous decomposed at temperatures above approximately 300 °C without melting.

Description of key information

The test item decomposes at a temperature >= 300 °C without melting.

Key value for chemical safety assessment
