Description of key information
No data is available for isooctane. However, data is available for 2,2,4-trimethylpentane and is being read across to using an analogue approach. A discussion and report on the read across strategy is given as an attachment in IUCLID Section 13.
The boiling range of 2,2,4 -trimethylpentane is 87 to 100°C at atmospheric pressure.
Key value for chemical safety assessment
Additional information
No data is available for isooctane. However, data is available for 2,2,4 -trimethylpentane and is being read across to using an analogue approach.A discussion and report on the read across strategy is given as an attachment in IUCLID Section 13.
Boiling point is measured at atmospheric pressure using ISO 3405 method. A range of 87 to 100°C covers all possible grades within this substance description if measured with the agreed method. Knovel (2003) gives a value of 99.2°C falling within this borderline values.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
