The particle size distribution of test item 2,4-Diaminobenzenesulfonic acid was determined by granulometric analysis. The particle size distribution was found to be in the range of 150 micron to 53 micron.
Vapor Pressure:
Data from various modeling databases suggests that the estimated vapor pressure of 2,4-Diaminobenzenesulfonic acid was 4.98E-009 mm Hg = 6.65E-007 Pa at 25 deg C
Partition coefficient:
Data from various modelling databases suggests that the experimental Partition coefficient (log Pow) 2,4-Diaminobenzenesulfonic acid was -4.65.
Data from various modelling databases suggests that the estimated Partition coefficient (log Pow) 2,4-Diaminobenzenesulfonic acid was -3.55.
These values indicates that the test substance is hydrophillic in nature.
Water Solubility:
Data from various modelling and authoritative databases suggests that the water solubility of the test chemical lies in the range of 6000 - 1000000 mg/l.
The water solubility value used for the chemical safety assessment of 2,4 -Diaminobenzensulfonic acid was 1000000 mg/l at 25 deg C.
This value indicates that 2,4 -Diaminobenzenesulfonic acid is highly soluble in water.
Surface tension:
Surface tension of test substance 2,4-Diaminobenzenesulfonic acid from chemspider database was estimated to be 86.6±3.0 dyne/cm.
Flash point:
The flash point of 2,4-Diaminobenzenesulfonic acid from TCI America material safety data sheet (88-63-1) was determined to be 300°C (572°F).
Autoflammability:
The chemical 2,4-diaminobenzenesulphonic acid does not catch fire spontaneously upon exposure to air at normal conditions of temperature and pressure. Thus the chemical is not likely to be "Auto flammable" and hence this end point was considered for waiver and the chemical is not considered to be "self igniting".
Flammability:
The chemical 2,4-diaminobenzenesulphonic acid has NFPA rating for Flammability reported to be 0. This suggests low likelihood of the chemical being flammable. Hence this end point was considered for waiver & the chemical is classified as "Non Flammable" for chemical safety assessment.
Explosiveness:
In accordance with column 2 of Annex VII of the REACH regulation, the study does not need to be conducted since there are no chemical groups associated with explosive properties present in the molecule of 2,4-diaminobenzenesulphonic acid. Thus, this end point was considered for waiver and the chemical is considered to be "Non explosive".
Oxidising Properties:
In accordance with column 2 of Annex VII of the REACH regulation, the substance 2,4-diaminobenzenesulphonic acid is incapable of reacting exothermically with combustible materials on the basis of the chemical structure. It is an organic substance containing oxygen atoms and no halogen atoms. Also, the oxygen atoms are not chemically bonded to nitrogen or oxygen. Thus, the chemcial is likely to be "Non-oxidising".
Viscosity:
In accordance with Section 2 of REACH Annex XI, information requirement section 7.17, this study cannot be conducted on solid materials or gases. According to ECHA Chapter 7 guidance, viscosity measurement is only relevant to liquids. The chemical 2,4-Diaminobenzenesulfonic acid (CAS No.88-63-1)is brown colored powder.Hence this study can be considered for waiver.
