Reference
Endpoint:
boiling point
Type of information:
experimental study
Adequacy of study:
key study
Study period:
March 2001
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: Study was carried out according to generally valid and internationally accepted testing guidelines and under GLP. The identity is not fully known. This is acceptable because the endpoint can be waived because of decomposition.
Qualifier:
according to guideline
Guideline:
EU Method A.2 (Boiling Temperature)
Qualifier:
according to guideline
Guideline:
OECD Guideline 103 (Boiling point/boiling range)
GLP compliance:
yes
Type of method:
differential scanning calorimetry
Decomposition:
yes
Decomp. temp.:
> 200 - < 310 °C

The scans show a broad exothermic peak between 200°C and 300°C. This exothermic behaviour is characteristic of decomposition and this was confirmed by the presence of dark brown residue (approximately 94% of the original sample mass) at the end of each scan. The third scan showed exothermic activity at ca. 210°C - 310°C. No boiling was observed in any of the scans.

Conclusions:
84989-41-3, AKD,
The test substance decomposes without boiling with decomposition occurring above 200°C

Description of key information

The test substance decomposes without boiling with decomposition occurring above 200°C

Key value for chemical safety assessment

Additional information

The study was carried out on CAS 84989-41-3 according to generally valid and internationally accepted testing guidelines and under GLP. The endpoint can be waived because of decomposition.
