1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to
Guideline:
OECD Guideline 102 (Melting point / Melting Range)
Deviations:
no
GLP compliance:
yes
Type of method:
capillary method
Specific details on test material used for the study:
- Purity: Molybdenum concentration of 10.2%
- Description: Brown, extremely viscous liquid
Key result
Melting / freezing pt.:
> 229 - < 235 °C
Decomposition:
yes
Remarks:
the melting temperature was determined to range from 235 K, at which the test material was slightly pliable and gum-like, to 229 K

Based on observations of the test material throughout the test, the melting temperature was determined to range from 235 K, at which the test material was slightly pliable and gum-like, to 229 K, at which the test material was crystalline.

Conclusions:
The melting temperature of the test material has been determined to range from 235 K (-38°C), at which it was slightly pliable and gum-like, to 229 K, (-44°C), at which it was crystalline.
Executive summary:

The melting temperature of the test material was conducted in a study performed to the standardized guideline OECD 102 under GLP conditions. The melting temperature of the test material has been determined to range from 235 K (-38°C), at which it was slightly pliable and gum-like, to 229 K, (-44°C), at which it was crystalline.
