Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Endpoint:
appearance / physical state / colour
Type of information:
read-across from supporting substance (structural analogue or surrogate)
Adequacy of study:
supporting study
Study period:
November 18th, 2015
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
test procedure in accordance with generally accepted scientific standards and described in sufficient detail
Justification for type of information:
REPORTING FORMAT FOR THE ANALOGUE APPROACH
The usage of information on Direct Blue 199 Na/NH4, which has the same main component and with a different counter ion, can be considered as suitable and appropriated because the difference in salification is expected to not influence the characteristics related to the specific end-point.
The impurity profile does not impact on the read across proposed. Details on the approach followed are included in the document attached to the IUCLID section 13.
Qualifier:
according to guideline
Guideline:
other: OECD Guideline 102 (Melting point / Melting Range)
Version / remarks:
adopted July 27, 1995
Qualifier:
according to guideline
Guideline:
other: EU Method A.1 (Melting / Freezing Temperature)
GLP compliance:
no
Physical state at 20°C and 1013 hPa:
solid
Form:
not specified
Conclusions:
Solid at 20 °C and 1013 hPa.
Executive summary:

The melting temperature of the test substance was investigated. The Differential Scanning Calorimetry method was used. The procedures used in the study were in accordance with OECD Test Guideline No.102. 

At the temperature of 230 °C an endothermic reaction was recorded, which was probably caused by the water evaporation. A second endothermic peak very low intensity was observed between 340 and 380 °C, caused by the thermal decomposition of the test substance. After the experiment the sample had lost of its mass and the residue had a black colour.

 

Conclusion

Solid at 20 °C and 1013 hPa.
