Description of key information

The relative density of undecan-1-ol is 0.8334 at 20°C.

Key value for chemical safety assessment

Relative density at 20C:

0.83

Additional information

The relative density of 0.8334 was determined in a reliable study.

It is supported by a value of 0.83 (at 20°C, relative to water at 4°C), taken from a reliable handbook, and various consistent results from other reference sources.

Discussion of trends in the Category of C6-24 linear and essentially-linear aliphatic alcohols:

The relative density values are similar across the category. Values are consistently within the range 0.80 - 0.90 at ambient temperature.
