Reference
Endpoint:
boiling point
Remarks:
Determination of the melting point and boiling point of 1-butyl-5-[(4-chlorophenyl)azo]-1,2-dihydro-6-hydroxy-4-methyl-2-oxonicotinonitrile according to OECD 102 / 103 resp. EU A.1 / A.2
Type of information:
experimental study
Adequacy of study:
key study
Study period:
From 22 OCTOBER 2018 to 06 NOVEMBER 2018
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to guideline
Guideline:
OECD Guideline 103 (Boiling Point)
Deviations:
no
Qualifier:
according to guideline
Guideline:
EU Method A.2 (Boiling Temperature)
Deviations:
no
GLP compliance:
yes (incl. QA statement)
Type of method:
method according to Siwoloboff
Key result
Decomposition:
yes
Remarks:
Boiling point In the pre-test boiling point following Siwolobioff the test item decomposed before boiling. Therefore the determination of billing point is technically not feasible under these test circumstances.
Decomp. temp.:
>= 270 °C
Conclusions:
Boiling point
In the pre-test boiling point following Siwolobioff the test item decomposed before boiling.
Therefore the determination of billing point is technically not feasible under these test circumstances.
No observations were made which might cause doubts on the validity of the study outcome. Therefore, the result of the study is considered valid.

Description of key information

The boiling point of the test item 1-butyl-5-[(4-chlorophenyl)azo]-1,2-dihydro-6-hydroxy-4-methyl-2-oxonicotinonitrile is technically not feasible as the test item decomposed before boiling.

Key value for chemical safety assessment
