Key result
Melting / freezing pt.:
< -11.52 °C
Atm. press.:
969.1 hPa
Remarks on result:
other: No other data given
Conclusions:
The Freezing point determination of Pentyl formate (CAS No.638-49-3) was done using crushed ice and salt.(type of bath). No freezing was observed up to -11.52°C. Hence, the freezing point was inferred to be less than -11.52 °C at 969.1 hPa.
Executive summary:

The Freezing point determination of Pentyl formate (CAS No.638-49-3) was done using crushed ice and salt.(type of bath). No freezing was observed up to -11.52°C. Hence, the freezing point was inferred to be less than -11.52 °C at 969.1 hPa.

Description of key information

The Freezing point determination of Pentyl formate (CAS No.638 -49 -3) was done using crushed ice and salt.(type of bath). No freezing was observed up to -11.52°C. Hence, the freezing point was inferred to be less than -11.52 °C at 969.1 hPa.

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
-11.52 °C

Additional information

The Freezing point determination of Pentyl formate (CAS No.638-49-3) was done using crushed ice and salt.(type of bath). No freezing was observed up to -11.52°C. Hence, the freezing point was inferred to be less than -11.52 °C at 969.1 hPa.

From the other reliable sources and authorative database melting point of the pentyl formate is determined to be -73.5 Deg C and -73 Deg C.
