Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

It is pyrophoric once isolated from solvent/volatiles and the aluminum-methyl bonds react violently with water releasing flammable methane gas.

Key value for chemical safety assessment

Flammability:
pyrophoric

Additional information

It also reacts with water emitting flammable gases (methane).

Justification for classification or non-classification

It is pyrophoric once isolated from solvent/volatiles and the aluminum-methyl bonds react violently with water releasing flammable methane gas.

It also reacts with water emitting flammable gases (methane).
