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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

EC number: 272-712-1 | CAS number: 68909-77-3 The residuum from the reaction of diethylene glycol and ammonia. It consists predominantly of morpholine-based derivatives such as [(aminoethoxy)ethyl]morpholine, [(hydroxyethoxy)ethyl]morpholine, 3-morpholinone, and 4,4'-(oxydi-2,1-ethanediyl)bis[morpholine].

Description of key information
The relative density of the test substance was determined to be 1.09 at 20.0 ± 0.5°C, using the pycnometer method, designed to be compatible with EC test method A.3, under GLP conditions (Butler and White, 2010).
Key value for chemical safety assessment
- Relative density at 20C:
- 1.09
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
