Interpretation of results:
other: non-flammable
Conclusions:
The flash point of 3,5-diaminobenzoic acid (CAS No. 535-87-5) is 238.6 °C at 979.7 hPa
Executive summary:

The flash point determination of 3,5-diaminobenzoic acid (CAS No. 535-87-5) 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 238.6°C at 979.7hPa.

Based on criteria mentioned in CLP regulation the chemical has flash point >than 60 degree C hence 3,5-diaminobenzoic acid (CAS No. 535-87-5) was considered to be non-flammable.
