Interpretation of results:
Division 1.4 (substances, mixtures and articles which present no significant hazard) based on GHS criteria
Conclusions:
Based on the screening procedure followed, the substance 7-[[2-[(aminocarbonyl)amino]-4-[(4-amino-6-chloro-1,3,5-triazin-2-yl)amino]phenyl] azo]naphthalene-1,3,6-trisulphonic acid (CAS No.- 35642-64-9) is considered to have marginal explosive properties and hence classified under explosive Division 1.6 based on CLP criteria.
Executive summary:

The screening procedure for explosive properties is based on the use of both theoretical considerations which is summarized as follows:

The substance 7-[[2-[(aminocarbonyl)amino]-4-[(4-amino-6-chloro-1,3,5-triazin-2-yl)amino]phenyl]azo]naphthalene-1,3,6-trisulphonic acid (CAS: 35642 -64 -9) contains an azo group and triazine group; two of the alert groups for explosive properties. Thus, following the screening procedure, the oxygen balance was calculated. The molecular formula is C20H16ClN9O10S3 and the molecular weight is 674.0504. These give an oxygen balance of –90.200. This is more positive than the –200 threshold.

Further testing data is not available.

Thus, based on the screening procedure followed, the substance 7-[[2-[(aminocarbonyl)amino]-4-[(4-amino-6-chloro-1,3,5-triazin-2-yl)amino]phenyl]azo]naphthalene-1,3,6 -trisulphonic acid(CAS: 35642 -64 -9) is considered to have marginal explosive properties and hence classified under explosive Division 1.6 based on CLP criteria.
