Conclusions:
The Freezing point of ETHYL BUTYRATE; CAS No. 105-54-4 was determined with Freezing Temperature Method and it was found to be less than -11.4 °C at 968.4 hPa.
Executive summary:

The Freezing point determination of ETHYL BUTYRATE (CAS No.105-54-4) was done using crushed ice and salt. No freezing was observed up to -11.4 °C. Hence, the freezing point was inferred to be less than -11.4 °C at 968.4 hPa.

Description of key information

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
-11.4 °C

Additional information

The Freezing point determination of ETHYL BUTYRATE (CAS No.105-54-4) was done using crushed ice and salt. No freezing was observed up to -11.4 °C. Hence, the freezing point was inferred to be less than -11.4 °C at 968.4 hPa.

Based on available data from various reliable sources such as authoritative databases and handbooks,the freezing point of test chemical was determined  to be -93 degree C.

Other supporting studies from various reliable sources such as authoritative databases and handbooks indicates that the freezing point of  test chemical was determined  to be in the range of -135 degree C to -85 degree C.
