Specific details on test material used for the study:

Batch no.: #120039110
Identity: carbamic acid, butylester (93.5 %), n-butanol (2.7%), ?n-Butylcarbamoyl carbamate (2.2 %), dibutyl carbonate (1.2 %)

Key result

Melting / freezing pt.:

48.9 °C

Conclusions:

Under the study conditions, the melting point of the test substance was determined to be 48.9°C (DSC method).

Executive summary:

A study was conducted to determine the melting point/freezing point of the test substance, according to OECD guideline 102 (DSC method). Duplicate specimens of the test substance were encapsulated in Al pans with pierced lids. Instrument were calibrated with an indium and zinc standard following internal procedure. Under the study conditions, the melting point of the test substance was determined to be 48.9°C (Sohar, 2016).
