Flash point

Administrative data

Endpoint:

flash point of flammable liquids

Data waiving:

study scientifically not necessary / other information available

Justification for data waiving:

the study does not need to be conducted because the flash point is only relevant to liquids and low melting point solids

Cross-reference

Cross-reference 1

Reason / purpose for cross-reference:

data waiving: supporting information

Reference

Endpoint:

appearance / physical state / colour

Type of information:

experimental study

Adequacy of study:

key study

Study period:

September 22, 2017

Reliability:

2 (reliable with restrictions)

Rationale for reliability incl. deficiencies:

other: Appearance based on observations from other testing endpoints conducted on this substance all at the same laboratory.

Reason / purpose for cross-reference:

reference to other study

Qualifier:

no guideline available

Principles of method if other than guideline:

Obervations based on the observations made during testing for other endpoints.

GLP compliance:

yes

Physical state at 20°C and 1013 hPa:

solid

Key result

Form:

solid

Remarks:

Pellets

Colour:

Off-white to pale yellow

Substance type:

organic

Conclusions:

The appearance of the lyophilised form of the test substance was found to be off-white to pale yellow powder. The test substance is placed on the market in pelleted forms.

Executive summary:

The physical state and appearance of the test substance, were visually observed during testing of other endpoints. The appearance of the lyophilised form of the test substance was found to be off-white to pale yellow powder (Scymaris, 2017). The test substance is placed on the market in pelleted forms.

Melting point results

Test substance	Initial melting point (°C)	Final melting point (°C)
1014.003	226	229
1014.003	224	230
1014.003	227	231
Mean melting point (°C)	226	230
Standard deviation	1.25	0.82
Relative standard deviation %	0.55	0.35

Conclusions:

Under study conditions, the melting point for the test substance was determined to be 226-230°C at 1 atm pressure.

Executive summary:

A study was conducted to determine the melting point of the test substance using the capillary method, according to OECD Guideline 102, in compliance with GLP. Under study conditions, the melting point for the test substance was determined to be 226-230°C at 1 atm pressure (Scymaris, 2017).
