Type of information:

experimental study

Adequacy of study:

key study

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

guideline study

Qualifier:

according to guideline

Guideline:

OECD Guideline 102 (Melting point / Melting Range)

Deviations:

no

GLP compliance:

yes (incl. QA statement)

Remarks:

There were no deviations from the study plan.

Other quality assurance:

other: German Chemicals Act (ChemG), Annex 1 and Directive 2004/10/EC

Type of method:

method to determine freezing temperature

Specific details on test material used for the study:

Batch No.: 0900243308

Melting / freezing pt.:

>= -35 - <= -32 °C

Atm. press.:

>= 988.8 - <= 994.4 mBar

Decomposition:

no

Sublimation:

no

following observations are made during freezing:

Stage A: The sample temperature decreases uniformly.

Stage B: The sample temperature rises suddenly as the test item crystallizes.

Stage C: The sample temperature remains constant for a short time.

Conclusions:

A freezing range according to the criteria of the guidelines could be determined at -32 °C to -35 °C. At the end of the measurement, the test item (Resorcinol diacetate) was solid.

Executive summary:

For Resorcinol diacetate a freezing range at -32 °C to -35 °C was determined.

Description of key information

A freezing range according to the criteria of the guidelines could be determined at -32 °C to -35 °C for Resorcinol diacetate.
