Description of key information

Melting point [tetrahydro-2-methylfuran]: <-20°C (<253 K) (EU Method A.1)

Additional information

A measured freeing point of <-20°C (<253 K) was determined for the substance in accordance with EU Method A.1 and in compliance with GLP. The result is considered to be reliable and selected as key study. This value is supported by a melting point of -136°C which was reported for the substance in a secondary source to which reliability could not be assigned.
