Additional information

The aim of this study was to determine the relative density of the test substance, Azuril ( Reaction mass of 3-(4-methyl-3-pentenyl)cyclohex-3-ene-1-carbonitrile and 4-(4-methyl-3-pentenyl)cyclohex-3-ene-1-carbonitrile). The study was conducted using a DMA-500 (Anton-Paar) Density Meter, following a method according to OECD 109 and EU Method A.3 guidelines.

The sample was introduced into the U-shaped borosilicate glass tube that is being excited to vibrate at its characteristic frequency. The frequency changes observed depend on the density of the sample. Through a precise determination of the characteristic frequency, the density of the sample is calculated. The temperature is controlled throughout the test.

The relative density of the test substance, Azuril ( Reaction mass of 3-(4-methyl-3-pentenyl)cyclohex-3-ene-1-carbonitrile and 4-(4-methyl-3-pentenyl)cyclohex-3-ene-1-carbonitrile), was determined to be 0.9230 at 20°C.
