Key result
Remarks on result:
other: 2,3-bis[(4-methylbenzoyl)oxy]succinic acid  (32634-68-7) 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:
2,3-bis[(4-methylbenzoyl)oxy]succinic acid  (32634-68-7) did not catch fire on being exposed to air at room temperature of 27°C pressure of 966 hPa. This indicates that 2,3-bis[(4-methylbenzoyl)oxy]succinic acid  (32634-68-7) is not auto-flammable.
Executive summary:

2,3-bis[(4-methylbenzoyl)oxy]succinic acid  (32634-68-7) did not catch fire on being exposed to air at room temperature of 27°C pressure of 966 hPa. This indicates that 2,3-bis[(4-methylbenzoyl)oxy]succinic acid  (32634-68-7) is not auto-flammable.
