Surface tension:

Based on the data from ACD labs, surface tension for chemical 2-methoxybenzoic acid was predicted to be 44.9 ± 3.0 dyne/cm.

 

Flash point:

The flash point determination of  2-methoxybenzoic acid (CAS No. 579-75-9)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 144°C at 970.4hPa.

 

Auto flammability:

The study does not need to be conducted because the substance is a solid having a melting point <= 160°C

 

Flammability:

2-methoxybenzoic acid does not indicate any ignition when the flame of bunsen burner having temperature of approximately 950°C is brought in contact with it. Thus it can be concluded that 2-methoxybenzoic acid is not flammable at high temperature. However since such high temperatures are not found under normal circumstances of transportation and use, thus 2-methoxybenzoic acid was considered non-flammable for chemical safety assessment.

 

Explosiveness:

The study does not need to be conducted because there are no chemical groups present in the molecule which are associated with explosive properties

 

Oxidising properties:

The study does not need to be conducted because the organic substance contains oxygen or halogen atoms which are chemically bonded only to carbon or hydrogen and hence, the classification procedure does not need to be applied
