Appearance: Dark red powder

Key result

Melting / freezing pt.:

> 350 °C

Atm. press.:

101.325 kPa

Decomposition:

yes

Decomp. temp.:

300 °C

Remarks on result:

other: no melting point until 350 °C.

No melting point until 350 °C detected.

Conclusions:

FAT 20202/H had no melting point until 350 °C; however, it started to undergo thermic decomposition at about 300 °C.

Executive summary:

The melting point of FAT 20202/H was investigated in a study conducted according to OECD Guideline 102. No melting point could be detected up to 350 °C, as the thermic decomposition of the test substance started at about 300 °C.
