2,4,6-trinitrobenzene-1,3,5-triamine

Boiling point

Administrative data

Endpoint:

boiling point

Data waiving:

study scientifically not necessary / other information available

Justification for data waiving:

the study does not need to be conducted because the substance is a solid which melts above 300°C

the study does not need to be conducted because the substance is a solid which decomposes before boiling

Justification for type of information:

JUSTIFICATION FOR DATA WAIVING
According to REACH Annex VII/column 2, the study does not need to be conducted for solids which melt above 300 °C, or for substances which decompose before boiling. As presented under Section 4.2, no melting transition occurs below 300°C, and decomposition occurs above this temperature. Therefore the present endpoint is not relevant.

Cross-reference

Reason / purpose for cross-reference:

data waiving: supporting information

Reference

No melting up to 300°C, followed by decomposition.

No experimental study is available for the substance.

From several secondary literature sources, in a Weight-of-Evidence approach, the melting point is unclear, with values ranging between ca 320 and 390°C. However, no transition is observed below 300°C, and decomposition occurs above this temperature. Therefore, no key data is retained.

It should also be noted that conformational/structural changes may occur in TATB, which may explain the different values.
