Reference
Endpoint:
melting point/freezing point
Type of information:
experimental study
Adequacy of study:
key study
Study period:
7 September - 17 November 2017
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to guideline
Guideline:
OECD Guideline 102 (Melting point / Melting Range)
Deviations:
no
Qualifier:
according to guideline
Guideline:
EU Method A.1 (Melting / Freezing Temperature)
Deviations:
no
Qualifier:
according to guideline
Guideline:
EPA OPPTS 830.7200 (Melting Point / Melting Range)
Deviations:
no
GLP compliance:

Specific details on test material used for the study:
SOURCE OF TEST MATERIAL
- Source and lot/batch No.of test material: RY-95-001
- Expiration date of the lot/batch: July 01, 2022

STABILITY AND STORAGE CONDITIONS OF TEST MATERIAL
- Storage condition of test material: at 20°C +/- 5°C, in the dark
Key result
Decomposition:
ambiguous
Decomp. temp.:
> 180 °C
Remarks on result:
not determinable
Remarks:
During the measurement a colour changing of the test item was ob-served. The first changing was observed at 180 °C the test item was red-orange, at 315 °C – whitish, at 325 °C – dark-red. At 360 °C the test item was black-silver; due to this a decomposition process is assumed. From 360 °C until 400 °C no more changes were observed.
Conclusions:
For Reactive Yellow 95 (meta) no melting point according to the criteria described in the guideline could be observed up to 400 °C.
Executive summary:

The determination of the melting point was performed by visual judgement using the capillary method.

In the preliminary test up to 400 °C no melting point as described in the guideline could be observed.

During the measurement a colour changing of the test item was observed. The first changing was observed at 180 °C the test item was red-orange, at 315 °C – whitish, at 325 °C – dark-red.
