Key result
Remarks on result:
other: 5-acetamido-2-aminobenzenesulphonic acid ignites only when the flame of bunsen burner having temperature of 950°C is brought in contact with it.Thus it can be concluded that substance is flammable only at high temperature of about 950°C.
Conclusions:
Trisodium [2-[[α-[[2-hydroxy-5-sulpho-3-[(2,5,6-trichloro-4-pyrimidinyl)amino]phenyl]azo]benzyl]azo]-5-sulphobenzoato(5-)] cuprate(3-) did not catch fire on being exposed to air at room temperature of 27°C pressure of 966 hPa. This indicates that Trisodium [2-[[α-[[2-hydroxy-5-sulpho-3-[(2,5,6-trichloro-4-pyrimidinyl)amino]phenyl]azo]benzyl]azo]-5-sulphobenzoato(5-)] cuprate(3-) is not auto-flammable.
Executive summary:

Trisodium [2-[[α-[[2-hydroxy-5-sulpho-3-[(2,5,6-trichloro-4-pyrimidinyl)amino]phenyl]azo]benzyl]azo]-5-sulphobenzoato(5-)] cuprate(3-) did not catch fire on being exposed to air at room temperature of 27°C pressure of 966 hPa. This indicates that  Trisodium [2-[[α-[[2-hydroxy-5-sulpho-3-[(2,5,6-trichloro-4-pyrimidinyl)amino]phenyl]azo]benzyl]azo]-5-sulphobenzoato(5-)] cuprate(3-) is not auto-flammable.
