Specific details on test material used for the study:

SOURCE OF TEST MATERIAL
- Source and lot/batch No.of test material: MA-3-HO-ANL 1600356
- Expiration date of the lot/batch: 31 Aug 2020
- Purity test date: 05 Feb 2018
- Purity: 96.9%

STABILITY AND STORAGE CONDITIONS OF TEST MATERIAL
- Storage condition of test material: At room temperature container flushed with nitrogen
- Stability under test conditions: Yes

Melting / freezing pt.:

< -83.5 °C

Atm. press.:

1 014 hPa

Decomposition:

no

Sublimation:

no

At the end of the storage period, the test item was still a liquid. It was concluded that the melting temperature was below storage temperature.

Conclusions:

Melting point < -83.5 °C at 1014 hPa, EU method A.1

Executive summary:

The melting point of MA-3 was determined by placing two subsamples of the test item for 19 hours at -21.1 ± 1.3 °C and at -83.5 ± 1.6 °C respectively. At the end of the storage period, the subsamples remained liquid.

The study was conducted in accordance with EU Method A.1 and was GLP compliant; therefore the study is considered reliable without restrictions.

Key result

Melting / freezing pt.:

-157 - -151 °C

Conclusions:

MA-3 has a pour point of -154 ± 3 °C.

Executive summary:

The pour point of MA-3 was determined. The source data was unavailable. Because the data was unavailable, the result is not assignable.

Description of key information

The melting point of MA-3 is < -83.5 °C at 1014 hPa, EU method A.1

Additional information

The melting point of MA-3 was determined by placing two subsamples of the test item for 19 hours at -21.1 ± 1.3 °C and at -83.5 ± 1.6 °C respectively. At the end of the storage period, the subsamples substance remained liquid after being held 19 hours at -83.5 °C. The study was conducted in accordance with EU Method A.1 and was GLP compliant; therefore the study is considered reliable without restrictions.

The pour point of MA-3 was also determined to be -154±3 °C. The source data was unavailable. Because the data was unavailable, the result and reliability is not assignable.
