Reference
Endpoint:
boiling point
Type of information:
experimental study
Adequacy of study:
key study
Study period:
2009-01-06 - 2009-02-20
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
other: The GLP study was conducted according to an internationally accepted guideline. All study parameters are based on the specific guideline.
Qualifier:
according to
Guideline:
OECD Guideline 103 (Boiling point/boiling range)
Deviations:
no
GLP compliance:
yes (incl. certificate)
Type of method:
method according to Siwoloboff
Boiling pt.:
270.7 °C
Atm. press.:
1 013 hPa
Decomposition:
yes
Decomp. temp.:
270.7 °C
Conclusions:
The boiling point of N-[(3(5)-Methyl-1 H-pyrazol-1 -yl)-methyl]acetamide was determined according to OECD guideline 103. A change in colour was observed, which is taken as sign for decomposition. As in two in¬dependent determinations, very similar boiling points were found, there are no doubts that the study is valid.
Therefore, the boiling point should be stated as 270.7 C (543.8 K) under decomposition.
Executive summary:

The boiling point of N-[(3(5)-Methyl-1 H-pyrazol-1 -yl)-methyl]acetamide was determined according to OECD guideline 103.

A change in colour was observed, which is taken as sign for decomposition. As in two in­dependent determinations, very similar boiling points were found, there are no doubts that the study is valid. Therefore, the boiling point should be stated as 270.7 C (543.8 K) under decomposition.
