The measured density ofp-Nitrobenzoic acid, compound with 2,2’,2”-nitrilotriethanol (1:1)was1478.9±7.21 kg/m3.The relative density ofp-Nitrobenzoic acid, compound with 2,2’,2”-nitrilotriethanol (1:1)()is 1.48.

Conclusions:
The measured density of p-Nitrobenzoic acid, compound with 2,2’,2”-nitrilotriethanol (1:1) was 1478.9 +- 7.21 kg/m3.
The relative density of p-Nitrobenzoic acid, compound with 2,2’,2”-nitrilotriethanol (1:1) is 1.48.
Executive summary:

A known weight of the test item was placed in the sample cell and its volume determined by the density tester. The density of the test item was calculated from its weight and volume.

The measured density ofp-Nitrobenzoic acid, compound with 2,2’,2”-nitrilotriethanol (1:1)was1478.9±7.21 kg/m3.

The relative density ofp-Nitrobenzoic acid, compound with 2,2’,2”-nitrilotriethanol (1:1)() is 1.48.

Description of key information

The relative density of p-Nitrobenzoic acid, compound with 2,2’,2”-nitrilotriethanol (1:1) was determined in a GLP study using the pycnometer method (Klimisch 1, Toxicoop, 2017).

The measured density of p-Nitrobenzoic acid, compound with 2,2’,2”-nitrilotriethanol (1:1) was 1478.9 +- 7.21 kg/m3. The relative density was determined to be 1.48.

Key value for chemical safety assessment

Relative density at 20C:
