(3-methoxy-2-methylpropyl)benzene

Melting point / freezing point

Link to relevant study record(s)

Reference

Endpoint:

melting point/freezing point

Type of information:

experimental study

Adequacy of study:

key study

Study period:

From September 11 to 22, 1997

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

guideline study

Remarks:

The study was conducted according to OECD/EC guideline, and under GLP. The substance is considered to be adequately characterised with its purity. Therefore full validation applies.

Qualifier:

according to guideline

Guideline:

OECD Guideline 102 (Melting point / Melting Range)

Deviations:

no

Qualifier:

according to guideline

Guideline:

EU Method A.1 (Melting / Freezing Temperature)

Deviations:

no

Principles of method if other than guideline:

Not applicable

GLP compliance:

yes

Remarks:

(no certificate)

Type of method:

other: method described in French Standard NF T 20-051 was used

Key result

Melting / freezing pt.:

< -50 °C

Remarks on result:

other: No freezing point detected in the range of measurement (room temperature to minus 50 °C)

The lower limit of calibration of the collector is minus 50 °C. At this temperature, the test substance is still a liquid, without evidence of viscosity increasing or crystallization.

For information only, the cooling of the test substance has been performed in liquid nitrogen.

With a non -calibrated collector, we have seen crystallization between minus 100 and minus 130 °C.

Conclusions:

No further testing required.

Executive summary:

The freezing point of the test substance was determined according to OECD 102/EU A1, test substance being a liquid at room temperature, the method described in French Standard NF T 20-051 was used.

 

No freezing point was detected in the range of measurement (room temperature to minus 50 °C).

Description of key information

Freezing point < -20 °C (< -50°C).
No further testing is required.

Additional information

A fully reliable experimental study, conducted according to a recognized OECD/EU/NF method, is available. It is considered as a key study. As no crystallisation was observed down to -50°C, the result is expressed as a limit value, and cannot be retained as key data.
