Conclusions:
The mean flash point of 3-methylsulphanilic acid(CAS No. 98-33-9) is 175°C at 977.0hPa.
Executive summary:

The flash point determination of 3-methylsulphanilic acid (CAS No. 98-33-9)was done following closed cup method using Pensky-Martens flash point apparatus. The test was conducted in replicates and mean flash point was determined to be 175°C at 977.0hPa. Based on criteria mentioned in CLP regulation the substance methyl 3-methylsulphanilic acid (CAS No. 98-33-9)was considered to be non flammable.
