Conclusions:

The density of test item ethyl formate (CAS No. 109-94-4) was determined following 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 determine to be 0.9149 g/cm3at 20 °C and 974.8hPa.

Executive summary:

The density of test item ethyl formate (CAS No. 109-94-4) was determined following OECD Guideline 109 and according to theIndian standard method for determination of density of liquids [IS 4730:1994 (Reaffirmed 2010)]using glass pyknometer. The density of the test item was determine to be 0.9149 g/cm³ at 20 °C and 974.8 hPa.

Description of key information
