Administrative data
Link to relevant study record(s)
- Endpoint:
- boiling point
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 16 August 2004 - 01 September 2004
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.2 (Boiling Temperature)
- GLP compliance:
- yes
- Type of method:
- differential scanning calorimetry
- Specific details on test material used for the study:
- Identity: Nomcort HK-P
Batch: 2-10-A
Purity: 100 %
Appearance: Solid
Expiration Date: April 29, 2007
Storage: At room temperature at about 20 °C - Key result
- Decomposition:
- yes
- Decomp. temp.:
- >= 380 °C
- Conclusions:
- In conclusion, the decomposition of NOMCORT HK - P was observed before boiling occurred .
Reference
The DSC-curve of the preliminary test (heating rate of 20 K/min from 2s0 c to 400°C) is
shown in Figure 1. One endothermic heat effect, the melting, was observed at 71.6°C. An
exothermic heat effect, decomposition of the test item, was detected starting at about 380°C.
After the experiment, the sample had lost about 69 % of its mass, was melted and black in
colour.
Description of key information
one Guideline study available
Key value for chemical safety assessment
Additional information
No Boiling point observed due to decomposition of the substance
