other: Experimental result using standard methods of analysis
Qualifier:
according to guideline
Guideline:
OECD Guideline 109 (Density of Liquids and Solids)
Principles of method if other than guideline:
Determination of the mass at a given temperature of a volume of the material contained in a density bottle (pyknometer) and determination of the volume of the latter by determining the mass of the corresponding volume of water at the same temperature. The density is obtained by dividing the mass of material by its volume.

Conclusions:
The mean density of n-Hexyl amine (CAS No. 111-26-2) is 0.7583 g/cm3 at 20 °C and 977.6 hPa.
Executive summary:

The density of test item n-Hexyl amine (CAS No. 111-26-2) was determined following OECD guideline 109 and according to the Indian standard method for determination of density of liquids [IS 4730:1994 (Reaffirmed 2010)]. The mass by volume ratio was determined using pyknometer. The mean density of the test item was found to be0.7583 gm/cm3at 20oC and 977.6 hPa.

Description of key information

In a test conducted by SSS (Euroope)AB,the density of test item n-Hexyl amine (CAS No. 111-26-2) was determined following OECD guideline 109 and according to the Indian standard method for determination of density of liquids [IS 4730:1994 (Reaffirmed 2010)]. The mass by volume ratio was determined using pyknometer. The mean density of the test item was found to be0.7583 gm/cm3at 20oC and 977.6 hPa

Additional information

In a test conducted by SSS (Euroope)AB,the density of test item n-Hexyl amine (CAS No. 111-26-2) was determined following OECD guideline 109 and according to the Indian standard method for determination of density of liquids [IS 4730:1994 (Reaffirmed 2010)]. The mass by volume ratio was determined using pyknometer. The mean density of the test item was found to be0.7583 gm/cm3at 20oC and 977.6 hPa.

Other supporting studies from reliable sources such as handbooks and authoritative database,also suggests that the density of chemical Hexylamine was between the range of 0.763 g/cm3 to 0.767 g/cm3.

As the data from lab has K1 reliability and the test was performed using OECD guidelines which has the value of density as 0.7583 g/cm3 thus considered as key study for the chemical safety assessment.
