2016-10-24 until 2017-04-26

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

comparable to guideline study

Qualifier:

equivalent or similar to guideline

Guideline:

OECD Guideline 113 (Screening Test for Thermal Stability and Stability in Air)

Version / remarks:

internal method 2011-0343801-92D (DTA/DSC)

Principles of method if other than guideline:

Samples of the test item and of a reference material are subjected to the same controlled temperature programme. The difference in energy input necessary to maintain identical temperatures between the test item and the reference material is recorded. When the test item undergoes a phase transition, the corresponding change of enthalpy gives an endothermic (melting) or exothermic (freezing) deviation from the base line of the temperature and heat flow record.

GLP compliance:

yes

Conclusions:

The test item phosphorothioyltris(oxybenzene-4,1-diylcarbamoyloxyethane-2,1-diyl) trisprop-2-enoate decomposes during heating process (85 - 350 °C)

Executive summary:

Thermal stability of the test item phosphorothioyltris(oxybenzene-4,1-diylcarbamoyloxyethane-2,1-diyl) trisprop-2-enoate was determined via Differential Thermal Analysis (DTA) / Differential Scanning Calorimetry (DSC). After the heating process (85 - 350 °C) a solid black residue remains in the crucible which indicates decomposition of the test item.

Description of key information
