Additional information

The density of test chemical was determined following OECD Guideline 109 and according to the IS 4730: 1994 (Reaffirmed 2010) – Method for Determination of Density of Liquids (First Revision) using glass pyknometer.  The density of the test chemical was determined to be 1.004g/cm3 at 20 °C and 976.2hPa.

Based on the data obtained from the reliable source, the density of test chemical was determined to be 1.0111g/cm³ at 20 °C.

Based on the data obtained from the reliable source, the density of the test chemical was determined to be 1.006 g/cc at 20°C.

Based on the data obtained from the secondary source, the density of the test chemical was determined to be 1.009 g/l.

Thus based on the data obtained from the various sources, density of test chemical ranges from 1.004g/cm3 to 1.006 g/cc.
