Conclusions:
The Freezing point determination of 2-ethoxy benzoic acid (pure)(CAS No. 134-11-2) was done using crushed ice and salt.. The determination was done on the basis of cooling curve (time vs temperature) obtained when the test item was placed in the cooling bath. The freezing point was determined to be 10.78°C at 976.4 hPa.
Executive summary:

The Freezing point determination of 2-ethoxy benzoic acid (pure)(CAS No. 134-11-2) was done using crushed ice and salt.. The determination was done on the basis of cooling curve (time vs temperature) obtained when the substance was placed in the cooling bath. The freezing point was determined to be 10.78°C at 976.4 hPa.

The determination was done on the basis of cooling curve (time vs temperature) obtained when the substance was placed in the cooling bath. The freezing point was determined to be 10.78°C at 976.4 hPa.

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
10.78 °C

Additional information

The Freezing point determination of 2-ethoxy benzoic acid (pure)(CAS No. 134-11-2) was done using crushed ice and salt.. The determination was done on the basis of cooling curve (time vs temperature) obtained when the substance was placed in the cooling bath. The freezing point was determined to be 10.78°C at 976.4 hPa.

Other supporting studies from reliabe sources such as authoritative database and handbooks suggests that freezing point of chemical 2-ethoxy benzoic acid was determined to be in the range of 19.4 degree C to 20.7 degree C.

As the data from lab has K1 reliability and the test was performed using standard methods of analysis which has the value of freezing point as 10.78 degree C,thus considered as key study for the chemical safety assessment
