Key result

Remarks on result:

other: 3H,3'H-2,2'-bi-1-benzothiophene-3,3'-dione 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:

3H,3'H-2,2'-bi-1-benzothiophene-3,3'-dione did not catch fire on being exposed to air at room temperature of 27°Cpressure of 966 hPa. This indicates that 3H,3'H-2,2'-bi-1-benzothiophene-3,3'-dione is not auto-flammable.

Executive summary:

3H,3'H-2,2'-bi-1-benzothiophene-3,3'-dione did not catch fire on being exposed to air at room temperature of 27°Cpressure of 966 hPa. This indicates that 3H,3'H-2,2'-bi-1-benzothiophene-3,3'-dione is not auto-flammable.
