RESULT:

The mean density ofDiphenyl sulphide(CAS no.139-66-2) is 1.104g/cm³at 20°C and 974.6 hPa.

Conclusions:

The mean density of test item Diphenyl sulphide (CAS No. 139-66-2) was determined following OECD Guideline 109 and according to the method IS 4730: 1994 (Reaffirmed 2010)–Method for Determination of Density of Liquids (First Revision) using glass pyknometer. The mean density of the test item was determine to be 1.104 g/cm3 at 20 °C and 974.6 hPa.

Executive summary:

The density of test item Diphenyl sulphide(CAS No.139-66-2) 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 mean density of the test item was determine to be1.104 g/cm³at 20^oC and 974.6 hPa.

Additional information

The density of test item Diphenyl sulphide (CAS No.139-66-2) 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 mean density of the test item was determine to be 1.104 g/cm3 at 20^oC and 974.6 hPa.

 

Based on the data from an authoritative database such as IFA GESTIS (2017); the density of test substance Diphenyl sulphide (CAS No. 139-66-2) was determined to be 1.11 g/cm3 at 20 degC.

 

As the data from experimental study has K1 reliability and the test was performed using OECD guideline which has the value of density as 1.104 g/cm3 at 20degC and 974.6 hPa, thus considered as key study for the purpose of chemical safety assessment.
