Executive summary:

A study was performed in order to investigate the relative density of DPTU (1,3-diphenylthiourea). The study was made with a protocol equivalent to ASTM 1895.

The relative apparent density of DPTU is determined to be 0.30 at 20°C.

Description of key information

According to an experimental measure made by MLPC, relative apparent density of DPTU (1,3-diphenyl-2-thiourea)  is about 0.30 , whereas the crystal volumic mass is about 1.2 - 1.3 g/cm3

Key value for chemical safety assessment

Relative density at 20C:
0.3

Additional information
