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.
Distribution modelling
Administrative data
- Endpoint:
- distribution modelling
- Type of information:
- migrated information: read-across from supporting substance (structural analogue or surrogate)
- Adequacy of study:
- supporting study
- Study period:
- 2010-04-13
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: Accepted calculation method with acceptable restrictions: Preference of aqueous media will be further increased by neutralization as this increases the water solubility.
