Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

No boiling point for 2M3BN (69.56%) : decomposes from 40°C (experimental)

Key value for chemical safety assessment

Additional information

A fully valid experimental study was provided, showing decomposition of technical 2M3BN 69.56% pure before boiling, starting from 40°C.

Two old supporting publications on synthesis provide an indicative BP of about 126°C; no details are given, only the raw data, therefore validity cannot be assigned. However it may be supposed that this value would refer to substance of higher purity (compared to the above registrant study) that would not undergo decomposition.
