Trihydrogen [29H,31H-phthalocyaninetrisulphonato(5-)-N29,N30,N31,N32]cuprate(3-), compound with N,N'-di(o-tolyl)guanidine (1:3)

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

Justification for type of information:

JUSTIFICATION FOR DATA WAIVING
The substance is a powder with no melting point, and that decomposes before boiling.

Cross-reference

2 (reliable with restrictions)

Rationale for reliability incl. deficiencies:

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

Qualifier:

no guideline followed

Principles of method if other than guideline:

Determination of the melting point by the thermoanalytical technique DSC

GLP compliance:

no

Type of method:

differential scanning calorimetry

Key result

Decomposition:

yes

Decomp. temp.:

ca. 230 °C

Remarks on result:

not determinable

Remarks:

The test item shows no melting point.

Conclusions:

The test item has no a melting point and decompose before boiling

Executive summary:

A determination of the thermal stability of the test item by DSC (Differential Scanning Calorimetry) was performed with a DSC Mettler TOLEDO DSC 1, using a perforated crucible.

The substance has no melting point and starts decomposing at ca. 230°C.
