Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information

Based on the flash point and structure considerations and practical experiences, it is concluded that AHTN is non-Flammable.

Key value for chemical safety assessment

non flammable

Additional information

Justification for classification or non-classification

The flash point of AHTN is >100°C, which is above the upper limit of 60°C set in the classification and labelling criteria of the CLP regulation.

AHTN does not contain any chemical group that might lead to spontaneous ignition a short time after coming into contact with air, damp air or water at room temperature (circa 20°C). Furthermore, no metals, transition metals, boron or silicon are present.

Based on structural considerations (absence of structural alerts) and practical experience over decades, it can be concluded that the test substance is incapable of developing a dangerous amount of (flammable) gas in contact with air, damp air or water.
