Administrative data

Endpoint:

appearance / physical state / colour

Type of information:

experimental study

Adequacy of study:

key study

Reliability:

2 (reliable with restrictions)

Rationale for reliability incl. deficiencies:

study well documented, meets generally accepted scientific principles, acceptable for assessment

Remarks:

The appearance of the test item is described in a reliable study report on the physical-chemical properties of the substance. Since no guideline was followed and no details on the methods are given, the description is considered as reliable with restrictions.

guideline study

Qualifier:

according to guideline

Guideline:

OECD Guideline 102 (Melting point / Melting Range)

Version / remarks:

July 27, 1995

Deviations:

no

GLP compliance:

yes

Type of method:

differential scanning calorimetry

Melting / freezing pt.:

>= -42 - <= -20.7 °C

Decomposition:

no

Remarks on result:

other: Pressure was not reported. It is assumed that melting point was tested at ambient conditions.

The peak corresponding to the melting of test item components was observed as a broad peak on the DSC chart. The range between the temperatures at the start and the end points of the peak was regarded as the melting range of test item. The measurement results are shown as follows:

Number of repetition	Appearance of measurement sample	Melting range (°C)
		Measured value	Average
1	Yellowish-brown liquid paste	-41.81 to -20.69	-42.0 to -20.7
2	Yellowish-brown liquid paste	-42.15 to -20.62

 

No adverse effects on the reliability of this test were noted.
