Guideline:

OECD Guideline 109 (Density of Liquids and Solids)

Principles of method if other than guideline:

The density of test item is determined by using pyknometer. It is the ratio of mass of the unit volume of test item at a stated temperature to mass of the same volume of gas free distilled water at a stated temperature.

GLP compliance:

no

Type of method:

other: Adapted from ASTM D 854-02

Conclusions:

The mean density of Nonan-2-one (CAS No. 821-55-6) is 0.8200 g/cm3at 20 °C and 981.8 hPa.

Executive summary:

The density of test itemNonan-2-one(CAS No. 821-55-6)was determined following OECD Guideline 109 and according to thefollowing OECD guideline 109 and according to the Indian standard method for determination of density of liquids [IS 4730:1994 (Reaffirmed 2010)]using glass pyknometer. The density of the test item was determined to be 0.8200 g/cm³at 20°Cand 981.8 hPa.

Additional information

The density of test substance Nonan-2-one(CAS No. 821-55-6)was determined following OECD Guideline 109 and according to thefollowing OECD guideline 109 and according to the Indian standard method for determination of density of liquids [IS 4730:1994 (Reaffirmed 2010)]using glass pyknometer. The density of the test item was determined to be 0.8200 g/cm³at 20°Cand 981.8 hPa.

Other supporting studies from various reliable sources such as authoritative database and handbooks suggests that the density of chemical Nonan-2-one was determined to be in the range of 0.817 g/cm3 to 0.832 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 0.82 g/cm3 at 20 degree C thus considered as key study for the chemical safety assessment.
