Additional information

The melting point determination of 1,3-Benzenedisulfonic acid, 4-[[5-(aminocarbonyl)-1- ethyl-1,6-dihydro-2-hydroxy-4-methyl -6-oxo-3-pyridinyl]azo]-6-[[4-[[3-[(4-amino-6-chloro- 1,3,5-triazin-2-yl)amino]-4-sulfophenyl]amino]-6-chloro-1,3,5-triazin-2-yl]amino]-b (CAS No.

93941-80-1) was done following OECD Guideline 102 and according to the metal block capillary method. The test was conducted in replicates and mean decomposition temperature was found to be 330°C at 970.4hPa.
