Density:

0.817 g/cm³

Temp.:

20 °C

Type:

relative density

Density:

0.816 other: no unit for rel. density

Remarks on result:

other: density of test item at 20 °C to water at 4 °C

Pre-test for viscosity

The test item was flowable and it was possible to inject the test item with a one way syringe.

First determination: A density of the test item of 0.8165 g/cm³ was measured at a temperature of 20 °C.

Second determination: A density of the test item of 0.8165 g/cm³ was measured at a temperature of 20 °C.

mean value: 0.8165 g/cm³at a temperature of 20 °C.

Relative density of the test substance at 20 °C to water at 4 °C (0,999975 g/cm³) is 0.8165.

Conclusions:

Relative density of the test substance at 20 °C to water at 4 °C (0.999975 g/cm3) is 0.8165.

Executive summary:

The density of the test item was calculated as 0.8165 ± 0.0001 g/cm³ at 20 ± 0.2 °C according to EU method A.3 and OECD guideline 109 and under GLP conditions.

This value represents the mean of two independent determinations ± the standard deviation. Standard deviation shows a very good correlation of the two determinations.

Correspondence of the values is very good. Therefore, the study is considered valid.

Relative density of the test substance at 20 °C to water at 4 °C (0,999975 g/cm³) is 0.8165.

Description of key information

The density of the test item was calculated as 0.8165 ± 0.0001 g/cm³at 20 ± 0.2 °C according to EU method A.3 and OECD guideline 109 and under GLP conditions.

This value represents the mean of two independent determinations ± the standard deviation. Standard deviation shows very good correlation of the two determinations.

Correspondence of the values is very good. Therefore, the study is considered valid.

Relative density of the test substance at 20 °C to water at 4 °C (0,999975 g/cm³) is 0.8165.

The density of hexanal was described also in several handbooks. Described properties are nearly the same: density of hexanal is 0.8335 g/cm³ at 20 °C. Relative density of the substance at 20 °C to water at 4 °C is 0.8335. This is in line with the experimentally derived value.

Key value for chemical safety assessment

Relative density at 20C:

0.817

Additional information

CRC Handbook:

Density of hexanal at 20 °C is 0.8335 g/cm³. Relative density of the substance at 20 °C to water at 4 °C is 0.8335.
