Specific details on test material used for the study:
Name of test material : 2-hydroxy-p-toluic acid (m cresotic acid)
Molecular formula :C8H8O3
Molecular weight :152.148 g/mol
Smiles notation :Cc1ccc(c(c1)O)C(=O)O
InChl :1S/C8H8O3/c1-5-2-3-6(8(10)11)7(9)4-5/h2-4,9H,1H3,(H,10,11)

Key result
Remarks on result:
other: 2-hydroxy-p-toluic 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:
2-hydroxy-p-toluic acid did not catch fire on being exposed to air at room temperature of 27°C pressure of 966 hPa. This indicates that 2-hydroxy-p-toluic acid is not auto-flammable.
Executive summary:

2-hydroxy-p-toluic acid did not catch fire on being exposed to air at room temperature of 27°C pressure of 966 hPa. This indicates that 2-hydroxy-p-toluic acid is not auto-flammable.
