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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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: 276-431-5 | CAS number: 72162-23-3 The high-boiling fraction separated by distillation from the products obtained from the reaction of nitric acid with cyclododecanol and cyclododecanone. Composed primarily of dodecanedioic acid, undecanedioic acid, and sebacic acid.

Description of key information
The density and relative density (20 4 D ) of the test substance were determined using a gas comparison stereopycnometer (Pycnomatic, Porotec, Frankfurt, Germany). With this method the volume of the test substance is measured in helium gas (Air Products, Amsterdam, The Netherlands)
in a calibrated cylinder of variable volume. After concluding the volume measurement, the mass of the sample is determined and the density calculated. The density of the test substance at 20ºC was 1.19 g/cm3 (1.19 x 10^3 kg/m^3).
Key value for chemical safety assessment
- Relative density at 20C:
- 1.19
Additional information
A gas comparison pycnometer was used for the determination of the density and relative density of
Corfree® M1 diacid mixture.
The density of the test substance at 20ºC was 1.19 g/cm3 (1.19 x 10^3 kg/m^3).
The relative density was 1.19.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
